Metallic coated
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.

MagiZinc® improves corrosion resistance with half the thickness of conventional zinc coatings, increasing yield, reducing cost and facilitating stronger, lighter products.
It offers improved automotive corrosion protection and higher process efficiency.

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 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.
