Uncoated steel flat products
Cold rolled products
Cold rolled low carbon steels for cold drawing or bending
these products are characterised by guaranteed maximum yield and tensile limits, and guaranteed minimum elongations, established on the basis of the different qualities, which determine the degree of cold forming possible, from simple bending to the most severe form of 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.
