            1) Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm. For thicknesses between 6.0 - 8.0 mm, sub-size Charpy V-specimens are used. The specified min value is then proportional to the cross-sectional area of the specimen compared to a full-size specimen (10x10 mm).

                    Fabrication and Other Recommendations

                    Welding, bending and machining

                    Strenx® Plus has very good weldability with good toughness and strength in the welds. Strenx® Plus has good forming and cutting performance.

                    Strenx® Plus is not suited for applications requiring hot working or heat treatments at temperatures above 400°C, since the material then maylose 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.
