Steel for forming
Our cold-rolled forming steels are available in a wide range of grades and corrosion-resistant coatings. Each grade is designed for specific applications and comes with a choice of surface quality. Extensive dimensional choice provides opportunities for cutting waste and maximising yield.
Our range of forming grades is available in both zinc coated and MagiZinc® (zinc-magnesium) coated. MagiZinc improves corrosion resistance with half the thickness of conventional zinc coatings, increasing yield, reducing cost and facilitating stronger, lighter products.
Applications
- Automotive components
- Building components
- Domestic appliances
- Tubes and sections

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+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.

Mechanical properties
Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction:
| EN 10346: 2015 | Grade | DX56D+Z | DX56D+ZM |
|---|---|---|---|
| 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.
