35CrMo steel pipe

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.

Delivery condition: annealing / tempering.

Hardness: ≦229 HBW

Characteristic:35CrMo has high static strength, impact toughness and high fatigue limit, harden ability is higher than 40Cr , higher creep strength and lasting strength under high temperature , long-term working temperature up to 500 ℃.

Application: 35CrMo alloy pipe is used to manufacture important parts of various machines that bear the impact, twist and high
