Product Description

China Supplier EN40B 722M24 32CrMo12 1.7361 Hot Rolled Plate Special Steel Rods

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.

6: Heat Treatment

Forging
    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.
