Properties

Mechanical properties

Metallic coated high-strength steel grades have the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction. Property range is indicated according to EN 10346, but properties meet equivalent VDA 239-100 specifications also.

Micro-alloyed steels

¹ Lower yield strength or 0.2% proof stress applies.
   BH2 refers to the increase of 0.2% proof stress after heating (bake hardening). Not applicable for hot-rolled substrate.
² Elongation after fracture A uses test piece length L₀ = 80 mm.
   For galvannealed grades (GA) the minimum elongation before fracture is lowered by 2%.
³ For galvannealed grades (ZF) the minimum r₉₀-value is lowered by 0.2.
