    General Product Description

    The high-strength structural steel at 900 MPa

    Strenx® 900MC is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 900 MPa.

    Strenx® 900MC meets and exceeds the requirements of S900MC in EN 10149-2. These cut-to-length sheets feature excellent thickness accuracy and surface quality in relation to strength level, providing an outstanding finish to the final products. Typical applications include advanced lifting devices and lighter transport solutions and components.  

    Dimension Range

    Strenx® 900 MC is available as cut to length sheets with mill edge in thicknesses of 0.118" - 0.393", widths up to 62.992" and lengths up to 511.81".

                    Fabrication and Other Recommendations

                    Welding, bending and machining

                    Strenx® 900MC has good welding, cold forming and cutting performance.

                    Strenx® 900MC is a cold forming steel not suited for heat treatments at temperatures above 752°F since the material then may lose its guaranteed properties.

                    For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.

                    Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
