Steel grades of hot rolled sheet pile sections

The whole range of ArcelorMittal’s hot rolled steel sheet piles can be delivered in steel grades according to the European standard EN 10248 – Part 1:2023, but note that not all profiles are available in all steel grades. Standardized yield strength f_y (Note: the value of R_eH is used in the European standard) start at 240 MPa and go up to 500 MPa. The new version of EN10248-1:2023 introduces new requirements on the steels: CEV values (carbon equivalent value) and impact properties (Charpy V-Notch test).

The tables below summarize the current availability.

For steel grades of cold formed sheet piles, see link below.

Special steel grades such as American ASTM A572 steel grades, steels with improved corrosion resistance, such as AMLoCor^® and ASTM A690, or steels with copper addition in accordance with EN 10248 – Part 1:2023, Chapter 7.2.4, can be supplied on request. A modified steel grade A690 with a higher yield strength is also available for some sheet pile sections.

We strongly recommend to our customers informing us of any surface treatment that will be applied to the product before placing orders. For instance, hot-dip galvanization can only be applied correctly to steel with a specific chemical composition (see EN 10248 – Part 1:2023, Chapter 7.4.3). Therefore, customers must mention in their enquiry that the sheet piles will be galvanized, and confirm it in the purchase order.

Steel grade availability may change at any time, without prior notice, so please contact us for updated information.
