Standard values for as-delivered condition (plate thickness of 0.787")<br />
Quality test<br />
Brinell hardness is measured according to ISO 6505 per heat and for every 88,000 pounds (40 mt).<br />
Hardness is measured approx. 0.04" (1 mm) under the surface. The heat analysis is provided as<br />
proof of the chemical composition.<br />
Tolerances and surface finish<br />
Unless otherwise agreed, tolerances according to EN 10029 (thickness<br />
tolerance according to class A, flatness tolerance according to class N)<br />
and surface finish according to EN 10163-A1 are valid.<br />
Marking<br />
In general, marking consists of:<br />
<strong>voestalpine</strong> symbol<br />
Steel grade designation<br />
Heat number<br />
Plate number<br />
Material testing certificate<br />
Type of certificate according to EN 10204 must be agreed upon ordering.<br />
Processing guidelines<br />
Cold forming<br />
Fracture elongation<br />
Yield strength Tensile strength L 0 = 5,65 √ S 0<br />
Steel grades MPa MPa %<br />
durostat 400 1,000 1,250 10<br />
durostat 450 1,100 1,400 9<br />
durostat 500 1,200 1,550 8<br />
durostat 400, durostat 450 and durostat 500 can be cold formed if the high hardness is taken into account.<br />
The prerequisite for cold forming is the proper preparation of the cut edges. Grinding of the flame- or<br />
shear-cut edges in the bending area is recommended. Due to the high level of hardness, bending must<br />
take place slowly and steadily.<br />
