Uncoated steel flat products
Cold rolled products
Cold rolled high strength steels for cold forming
these products are characterised by guaranteed minimum yield, rupture and elongation limits.
They are ideal for cold forming, from bending to moulding, while maintaining high resistance values. They have minimum resilience values at low temperatures and are suitable for obtaining resistant and resilient parts in moderately complex (quality grades S315, 355, 420MC) and light shapes, as the thicknesses can be reduced considerably. They are widely used, for example, in the automobile and shelving sectors.
The tables below show only the main characteristics of the products listed and not all the technical supply conditions. For further details, please refer to the full contents of the standards mentioned on this page.
