ArcelorMittal

Steel grades for Hot rolled sections

All the sections can be delivered in steel grades according to EN 10248-1, but not all sections are available in all steel grades. Below table summarizes the current possibilities. Special steel grades like S 460 AP, American ASTM A 572 steel grades, steels with improved corrosion resistance like AMLoCor and ASTM A 690, or steels with copper addition in accordance with EN 10248 Part 1 Chapter 10.4 can be supplied on request. A modified steel grade A 690 with higher yield strength is also available upon request. Please contact us for updated information.

Galvanisation has an influence on the chemical composition of the steel and must therefore be specified in the purchase orders. We strongly recommend informing us of all surface treatment to be applied to the product when placing orders. ArcelorMittal can also provide steel grades complying with other standards (see table below).
