    General Product Description

    The extra-high tough steel for structural wear parts

    Hardox® HiTuf is an abrasion-resistant plate with guaranteed impact toughness. With a nominal hardness of 350 HBW, it’s a good choice for structural wear parts like thick cutting edges, demolition tools and rippers.

    Dimension Range

    Hardox® HiTuf is available in thicknesses of 1.575 – 6.299". Hardox® HiTuf is available in widths up to 131.889" and lengths up to 575.984". For thicknesses over 4.921" preferred width is 64.960". More detailed information on dimensions is provided in the dimension program.

        1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.019 – 0.118" below surface. At least one test specimen per heat and 40 tonnes. The nominal thickness of supplied plates will not deviate more than +/- 0.590" from the thickness of the test specimen used for hardness testing. For sheet the Brinell hardness test is according to EN ISO 6506-1 on each heat treatment individual/coil. Hardness is measured on a milled surface 0.012 - 0.079" below surface.

        Hardox® wear plate is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum surface hardness.

                    Fabrication and Other Recommendations

                    Welding, bending and machining

                    Recommendations can be found in SSABs brochures at www.hardox.com or consult Tech Support.

                    Hardox® HiTuf is not intend for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 842ºF .

                    Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
