Properties
Mechanical properties
Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction:
| EN 10346: 2015 | Grade | DX52D+Z/+ZF/+ZM |
|---|---|---|
| Yield strength 1 Re | N/mm² | 140 - 300 3 |
| Tensile strength Rm | N/mm² | 270 - 420 |
| Elongation 2 | % | 26 |
| Min. r-value | - | |
| Min. n-value | - |
1. If the yield point is not pronounced, the values apply to the 0.2% - proof strength Rp0.2 ; if the yield strength is pronounced, the values apply to the lower yield point ReL.
2. Decreased minimum elongation values apply for product thickness t ≤ 0.50 mm (minus 4 units) and for 0.50 mm ≤ t ≤ 0.70 mm (minus 2 units).
Elongation after fracture A uses test piece length L0 = 80 mm.
3. This value applies to skin-passed products only (surface qualities B and C).

Properties
Mechanical properties
Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction:
| EN 10346: 2015 | Grade | DX54D+Z | DX54D+ZF/+ZM |
|---|---|---|---|
| Yield strength 1 Re | N/mm² | 120 - 220 | 120 - 220 |
| Tensile strength Rm | N/mm² | 260 - 350 | 260 - 350 |
| Elongation 2 | % | 36 | 34 |
| Min. r-value 3 | 1.6 | 1.4 | |
| Min. n-value | 0.18 | 0.18 |
1. If the yield point is not pronounced, the values apply to the 0.2% - proof strength Rp0.2 ; if the yield strength is pronounced, the values apply to the lower yield point ReL.
2. Decreased minimum elongation values apply for product thickness t ≤ 0.50 mm (minus 4 units) and for 0.50 mm ≤ t ≤ 0.70 mm (minus 2 units).
Elongation after fracture A uses test piece length L0 = 80 mm.
3. For t > 1.5 mm, the minimum r90 - value reduced by 0.2 applies.

|---|---|---|---|
| Yield strength 1 Re | N/mm² | 120 - 180 | 120 - 180 |
| Tensile strength Rm | N/mm² | 260 - 350 | 260 - 350 |
| Elongation 2 | % | 39 | 37 |
| Min. r-value 3 | 1.9 | 1.7 4 | |
| Min. n-value | 0.21 | 0.20 4 |
1. If the yield point is not pronounced, the values apply to the 0.2% - proof strength Rp0.2 ; if the yield strength is pronounced, the values apply to the lower yield point ReL.
2. Decreased minimum elongation values apply for product thickness t ≤ 0.50 mm (minus 4 units) and for 0.50 mm ≤ t ≤ 0.70 mm (minus 2 units).
Elongation after fraction A uses test piece length L0 = 80 mm.
3. For t > 1.5 mm, the minimum r90 - value reduced by 0.2 applies.
4. For t ≤ 0.70 mm, the minimum r90 - value reduced by 0.2 and minimum n90- value reduced by 0.01 apply.

Three types of metallic coating are available:
Pure zinc
Galvanised steel (+Z) is coated with an almost pure zinc coating (>99% zinc).
Zinc-iron alloy
Galvannealed steel (+ZF) is coated with a zinc coating containing approximately 8-12% iron.
For further information on our galvannealed products please visit our Automotive catalogue.
MagiZinc
MagiZinc steel (+ZM) is coated with a zinc coating containing additional magnesium and aluminium.
Coating weight
| Coating | Minimum | Maximum |

Mechanical properties
Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction:
| EN 10346: 2015 | Grade | DX57D+Z | DX57D+ZM |
|---|---|---|---|
| Yield strength 1 Re | N/mm² | 120 - 170 | 120 - 170 |
| Tensile strength Rm | N/mm² | 260 - 350 | 260 - 350 |
| Elongation 2 | % | 41 | 39 |
| Min. r-value 3 | 2.1 | 1.9 4 | |
| Min. n-value | 0.22 | 0.21 4 |
1. If the yield point is not pronounced, the values apply to the 0.2% - proof strength Rp0.2 ; if the yield strength is pronounced, the values apply to the lower yield point ReL.
2. Decreased minimum elongation values apply for product thickness t ≤ 0.50 mm (minus 4 units) and for 0.50 mm ≤ t ≤ 0.70 mm (minus 2 units).
Elongation after fraction A uses test piece length L0 = 80 mm.
3. For t > 1.5 mm, the minimum r90 - value reduced by 0.2 applies.
4. For t ≤ 0.70 mm, the minimum r90 - value reduced by 0.2 and minimum n90- value reduced by 0.01 apply.
