  • Quick Details

    1: DIN S355K2 steel introduction

          S355K2 belongs to the European standard low alloy high strength structural steel plate, "S" stands for structural steel, "355" stands for the specified minimum yield point (MPa), which will be reflected in its mechanical properties. "K2" means that the impact energy at -20℃ is not less than 40 J ("K" means the required 40 J and "2" means -20℃). It carries high strength, high toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, welding and easy processing properties.

    4: DIN S355K2 steel mechanical properties

        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

    6: Delivery condition

        For hot forged  bar, usually the delivery condition is hot forged, annealed/solid solution, rough turned/Black surface.
        For hot rolled bar, usually the delivery condition is hot rolled, annealed/solid solution, Black surface.
        For hot rolled plate, usually the delivery condition is hot rolled, annealed/solid solution, black surface.

        For cold drawn bar, usually the delivery condition is cold drawn, annealed/QT, peeled/black surface
