Steel grades for Hot rolled sections
AZ, AU, PU, AS and HZM sections are delivered in the steel grades based on EN 10248-1 mentioned below. GU sections are available in S 270GP and S 355 GP (please contact us for other steel grades).
ArcelorMittal can also provide steel grades complying with other standards. The table below compares the main standards used worldwide. For chemical composition, see the corresponding standard.
Steel grades AMLoCor, S 460 AP, A 572 Gr. 65 as well as special steels with improved corrosion resistance ASTM A 690, or 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.
