What is 35CrMo steel material

What is 35CrMo steel material? 35CrMo steel material belongs to alloy structural steel. 35 refers to the carbon content of about 35%, Cr is chromium, and Mo is molybdenum.

35CrMo steel material has high static strength, high impact toughness, high fatigue limit, higher hardenability than 40Cr steel, high temperature resistance, long-term working temperature can reach 500 ℃, poor welding performance.

The main applications of 35CrMo steel material are: it can be processed into important structural parts working under high load, such as the transmission parts of vehicles and engines; the rotor, main shaft, transmission shaft of heavy load and large section parts of turbogenerator.

Chemical composition of 35CrMo steel material:
Carbon C: 0.32-0.40
Silicon Si: 0.17-0.37
Mn: 0.40-0.70
Sulfur S: allowable residual content ≤ 0.035
Phosphorus P: allowable residual content ≤ 0.035
Cr: 0.80-1.10
Ni: allowable residual content ≤ 0.030
Cu: allowable residual content ≤ 0.030
Mo: 0.15-0.25

The mechanical properties of 35CrMo steel material were as follows:
Tensile strength σb (MPA): ≥ 985 (100), yield strength σs (MPA): ≥ 835 (85), elongation δ5 (%): ≥ 12, area reductionψ(%): ≥ 45, impact energy Akv (J): ≥ 63, hardness: ≤ 229HB.
