    General Product Description

    The high-strength structural steel at 1100 MPa

    Strenx® 1100MC is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 1100 MPa for stronger and lighter structures.

    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 a wide range of parts and components such as demanding load-bearing structures. 

    Dimension Range

    Strenx® 1100MC is available as cut to length sheets with mill edge in thicknesses of 3.00 - 8.00 mm, widths up to 1700 mm and lengths up to 16 meters.

      Comparison

        The mechanical properties are tested in the longitudinal direction.

        1) If ReH is not applicable then Rp0.2 is used.

        2) For both longitudinal and transverse direction.

                    Fabrication and Other Recommendations

                    Welding, bending and machining

                    Strenx® 1100MC has good welding, cold forming and cutting performance.

                    Strenx® 1100MC is not suited for applications requiring hot working or heat treatments at temperatures above 200°C 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.
