    General Product Description

    SSAB Boron 36 is steel for quench- and press hardening. The degree of hardness and toughness that can be achieved after heat-treatment will provide the final products with wear- and shock resistance properties that assure longer lifetime.

    Dimension Range

    SSAB Boron 36 is available in thickness range 2.00-15.00 mm and widths up to 1800 mm as coils, slit coils and CTL. Lengths up to 16 meters as cut to length.

        Bending radius

        Minimum bending radius of hot rolled SSAB Boron 36 strip products is 3 x sheet thickness. A tighter bending radius, 1 x sheet thickness, can be guaranteed for the annealed strip products. For further information, please contact SSAB’s Tech Support.

        Material Testing

        A test certificate according to EN 10204/2.2 (chemical composition) is part of the delivery.

        A test certificate according to EN 10204/3.1 can be provided by special agreement only.

                Tolerances

                SSAB Boron steels are delivered with SSAB Boron tolerances which meet and exceed the requirements in corresponding EN standards. Tighter tolerances are available on request.

                Thickness

                Hot rolled coils and sheet products: according to SSAB Boron thickness tolerances that exceed EN 10051 and correspond to 2/3 of EN 10051 as default value.

                Length and Width

                Hot rolled coils and sheets with mill edges: SSAB Boron width tolerances are corresponding to -0/+20 mm.

                Hot rolled coils and sheets with cut edges: SSAB Boron width tolerances are corresponding to -0/+2 mm.

                Shape

                Hot rolled coils and sheets: SSAB Boron is delivered with shape tolerances according to EN 10051. Tighter shape tolerances are available on request.

                Flatness

                Hot rolled sheets: SSAB Boron tolerances guarantee a maximum flatness deviation of 6 mm/m in addition to the EN 10051 flatness requirements. Flatness guarantees only apply for cut to length sheets.

                Surface Properties

                Hot rolled strip products: According to EN 10163-2 Class A, Subclass 3.

                Delivery Conditions

                Hot rolled coils and sheets are delivered in as-rolled or by separate agreement annealed condition.

                Surface Condition

                Hot rolled strip products are available in non-pickled, pickled dry or pickled & oiled condition.

                Fabrication and Other Recommendations

                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.
