Surface quality
Surface quality A
Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.
Surface quality B
The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.
Inspected side
As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.
Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Other surface textures are available to meet your requirements - please contact us for details.
Preservative oil
The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.
Surface cleanliness
Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.

Properties
Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Tata Steel | Grade | Ymvit 01 |
|---|---|---|
| EN 10209: 2013 | Grade | DC01EK |
| Max. yield strength Re 1,2,3 | N/mm² | 270 |
| Tensile strength Rm | N/mm² | 270 - 390 |
| Elongation 3 | % | 30 |
| r-value | r90 | - |
| ravg | - | |
| FLD | Yes/No | - |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
Chemical composition
Tata Steel complies with the following cast analysis:
| Tata Steel Ymvit | Grade | Ymvit 01 |
|---|---|---|
| EN 10209: 2013 | Grade | DC01EK |
| C | Max. | 0.09 |
| Mn | Max. | 0.50 |
| P | Max. | 0.030 |
| S | Max. | 0.050 |
| Ti | Max. | - |
The elements P and Cu are kept within certain limits to ensure that the reactivity of the steel surface is as constant as possible. Under normal conditions this leads to a reproducible enamelling result.
All values are in weight%.

1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
6. For design purposes, a lower yield strength ReL of at least 120 N/mm² can be assumed.

Coil welds
For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. You can find details on how to get in touch with us in 'Contact Us' below.

EN-EngineeringAutomotive-Product-Cold-rolled-All Grades Surface aspectsTSE
Surface quality
Surface quality A
Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.
Surface quality B
The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.
Inspected side
As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.
Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Preservative oil
The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.
Surface cleanliness
Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.
EN-Engineering-Product-Cold-rolled-Ymvit enamelling-Ymvit 04 plus-Properties TSN
Properties
Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Tata Steel | Grade | Ymvit 04 plus |
|---|---|---|
| EN 10209: 2013 | Grade | DC04EK |
| Max. yield strength Re 1,2,3 | N/mm² | 210 |
| Tensile strength Rm | N/mm² | 270 - 350 |
| Elongation 3 | % | 38 |
| r-value | r90 | - |
| ravg | - | |
| FLD | Yes/No | - |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
Chemical composition
Tata Steel complies with the following cast analysis:

Coil welds
For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. You can find details on how to get in touch with us in 'Contact Us' below.

EN-EngineeringAutomotive-Product-Cold-rolled-All Grades Surface aspectsTSE
Surface quality
Surface quality A
Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.
Surface quality B
The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.
Inspected side
As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.
Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Other surface textures are available to meet your requirements - please contact us for details.
Preservative oil
The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.
Surface cleanliness
Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.
EN-Engineering-Product-Cold-rolled-Ymvit enamelling-Ymvit Ultra 03-Properties TSN
Properties
Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Tata Steel | Grade | Ymvit Ultra 03 |
|---|---|---|
| EN 10209: 2013 | Grade | DC03ED |
| Max. yield strength Re 1,2,3 | N/mm² | 240 6 |
| Tensile strength Rm | N/mm² | 270 - 370 |
| Elongation 3 | % | 34 |
| r-value | r90 | - |
| ravg | - | |
| FLD | Yes/No | - |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
6. For design purposes, a lower yield strength ReL of at least 120 N/mm² can be assumed.
Chemical composition
Tata Steel complies with the following cast analysis:
| Tata Steel Ymvit | Grade | Ymvit Ultra 03 |
|---|---|---|
| EN 10209: 2013 | Grade | DC03ED |
| C | Max. | 0.004 |
| Mn | Max. | 0.40 |
| P | Max. | 0.035 |
| S | Max. | 0.050 |
| Ti | Max. | - |
The elements P and Cu are kept within certain limits to ensure that the reactivity of the steel surface is as constant as possible. Under normal conditions this leads to a reproducible enamelling result.
All values are in weight%.

Coil welds
For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. You can find details on how to get in touch with us in 'Contact Us' below.

EN-EngineeringAutomotive-Product-Cold-rolled-All Grades Surface aspectsTSE
Surface quality
Surface quality A
Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.
Surface quality B
The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.
Inspected side
As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.
Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Other surface textures are available to meet your requirements - please contact us for details.
Preservative oil
The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.
Surface cleanliness
Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.
EN-Engineering-Product-Cold-rolled-Ymvit enamelling-Ymvit Ultra 04-Properties TSN
Properties
Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Tata Steel | Grade | Ymvit Ultra 04 |
|---|---|---|
| EN 10209: 2013 | Grade | DC04ED |
| Max. yield strength Re 1,2,3 | N/mm² | 210 5, 6 |
| Tensile strength Rm | N/mm² | 270 - 350 |
| Elongation 3 | % | 38 |
| r-value | r90 | - |
| ravg | - | |
| FLD | Yes/No | Yes |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
6. For design purposes, a lower yield strength ReL of at least 120 N/mm² can be assumed.
Chemical composition
Tata Steel complies with the following cast analysis:
| Tata Steel Ymvit | Grade | Ymvit Ultra 04 |
|---|---|---|
| EN 10209: 2013 | Grade | DC04ED |
| C | Max. | 0.004 |
| Mn | Max. | 0.40 |
| P | Max. | 0.030 |
| S | Max. | 0.050 |
| Ti | Max. | - |
The elements P and Cu are kept within certain limits to ensure that the reactivity of the steel surface is as constant as possible. Under normal conditions this leads to a reproducible enamelling result.
All values are in weight%.

EN-EngineeringAutomotive-Product-Cold-rolled-All Grades Surface aspectsTSE
Surface quality
Surface quality A
Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.
Surface quality B
The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.
Inspected side
As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.
Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Other surface textures are available to meet your requirements - please contact us for details.
Preservative oil
The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.
Surface cleanliness
Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.
EN-Engineering-Product-Cold-rolled-Ymvit enamelling-Ymvit Extra 06-Properties TSN
Properties
Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Tata Steel | Grade | Ymvit Extra 06 |
|---|---|---|
| EN 10209: 2013 | Grade | DC06ED |
| Max. yield strength Re 1,2,3 | N/mm² | 190 6 |
| Tensile strength Rm | N/mm² | 270 - 350 |
| Elongation 3 | % | 38 |
| r-value | r90 | 1.9 |
| ravg | 1.6 | |
| FLD | Yes/No | Yes |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
6. For design purposes, a lower yield strength ReL of at least 120 N/mm² can be assumed.
Chemical composition
Tata Steel complies with the following cast analysis:
| Tata Steel Ymvit | Grade | Ymvit Extra 06 |
|---|---|---|
| EN 10209: 2013 | Grade | DC06ED |
| C | Max. | 0.004 |
| Mn | Max. | 0.35 |
| P | Max. | 0.020 |
| S | Max. | 0.050 |
| Ti | Max. | 0.30 |
The elements P and Cu are kept within certain limits to ensure that the reactivity of the steel surface is as constant as possible. Under normal conditions this leads to a reproducible enamelling result.
All values are in weight%.
