Uncoated steel flat products
Hot rolled products
Continuously hot rolled low carbon steels for cold forming
these products are characterised by guaranteed maximum yield and tensile limits and guaranteed minimum elongation established on the basis of the different qualities, which determine the degree of forming, from simple bending to the most severe moulding.
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.
