  • Quick Details

    1: 21CrMoV5-7 steel introduction

        21CrMoV5-7 Steel is a high quality High Temperature Alloy Structural steel, which belongs to the alloy steel for fasteners with high or low temperature performance. It has high strength and good performance after heat treatment, and is generally used in quenched and tempered state. 21CrMoV5-7 steel,also refers to DIN 1.7709, is defined as pearlitic heat-resistant steel with high content Cr and Mo as per EN 10269 Standard.

    Application  21CrMoV5-7 is used for engineering structural, like high tensile shafts, bolts and nuts, gears, pinions and spindles. Locomotive traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load of connecting rod and a spring clip,21CrMoV5-7 steel can also be used to under 2000 m deep well of oil drill pipe joint and the fishing tool, and can be used for bending machine mould, etc.

    6: Heat Treatment
        Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.

    7: Delivery condition

        For hot forged  bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.
        For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
        For hot forged block, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface
        For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
        For cold drawn bar, usually the delivery condition is cold drawn, annealed/QT, peeled/black surface
