Mechanical properties

Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction.
Not in EN 10346: 2015. Tata Steel’s own specification. Properties exceed VDA 239-100 CR5-GI.

Tata Steel Grade DX58
Yield strength Re N/mm² 120 - 155
Tensile strength Rm N/mm² 260 - 310
Elongation % 43
Min. r-value   2.30
Min. n-value   0.225
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.
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.
