DIN 32CrMo12/1.7361 | BS EN40B/722M24 Engineering Steel
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.

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: 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 rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
