  • Quick Details

    1: 18NiCrMo5 steel introduction

        18NiCrMo5 is a steel with good mechanical properties, suitable for carburizing heat treatment. In fact, it is the most famous and used steel in Italy among special case-hardened steels. Medium high hardenability and good machinability. It is available in the form of rolled bars, peeled or drawn bars and forged bars. 18NiCrMo5 steel is generally used in the quenched and tempered condition or carburized and quenched condition.

    4: 18NiCrMo5 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.

    Application  18NiCrMo5 is widely used in the production of wear parts such as gears, pinions, bushings, camshafts.

    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
