  • Quick Details

    1: 32CrMo12 steel introduction

        32CrMo12 steel is a nitriding steel which has at least 2.8Cr%,0.3%Mo as strengthening elements as per EN10250 standard.Similar with 30CrMo12,31CrMo12, it has a high tensile strength 880 - 1230 MPa after QT.32CrMo12 has high surface hardness and wear resistance after nitrided,but this material is difficult to weld and should therefore not be used in welded constructions.

    4: 32CrMo12 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.

    32CrMo12 is used in automotive and general mechanical engineering components which requires high hardness and wear resistance,also suitable for gear wheels, cylinders, drills, connecting rods, shafts, extruders, guides, thread gauges with relatively large-cross section,pins, spindles and bolts..

    6: Heat Treatment

        32CrMo12 steel forging temperature:900 – 1100°C ,cooling as slowly as possible in sand after forged.
    Heat Treatment
        Normalizing:  880 – 920°C,Cooling in air
        Soft Annealing:650 – 700°C,Cooling in furnace,Hardness:max 248 HB
        Hardening:890 – 940°C,water or oil quench
        Tempering:550 – 740°C,Cooling in air
        Nitriding: 480-570°C. Hardness after nitridng is 480-570 HV1.

    7: Delivery condition
        For hot forged rolled bar, usually the delivery condition is hot forged or rolled, annealed/QT, rough turned/Black surface.
        For hot forged or hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
        For hot forged plate, 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.
