Surface aspects

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%.

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.

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 aspects

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%.

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:

Tata Steel Ymvit Grade Ymvit 04 plus
EN 10209: 2013 Grade DC04EK
C Max. 0.08
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%.

Surface aspects

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%.

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%.

Surface aspects

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%.

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.

Out-of-squareness (products supplied as cut sheets only)

The deviation does not exceed 1% of the actual width of the sheet according to the EN 10131: 2006 standard. The deviation from the edge camber does not exceed 5 mm for a length of 2 metres as specified in EN 10131: 2006.

 

Flatness (products supplied as skin-passed cut sheets only)

Flatness complies with EN 10131: 2006
If there is a dispute about the flatness of material that was ordered to the special tolerances shown in table 8 of EN 10131:2006, then the minimum acceptable standards of flatness described below must be verified.
Criteria in case of disputes over special (FS) flatness tolerances (ReL < 260 N/mm2)

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.
