1. The main characteristics of 20CrMn
Carburizing steel, high strength, toughness, good harden ability. After heat treatment, the performance is better than 20Cr.Quenching deformation, low temperature toughness and good machine ability, good welding property; but low generally in the carburizing and quenching or quenching and tempering after use.
2. Chemical composition
C:0.17 ~ 0.23 Si:0.17 ~ 0.37 Mn:0.90 ~ 1.20 Cr:0.90 ~ 1.20
S: allows the residual sulfur content is less than 0.035
P: allows the residual phosphorus content is less than 0.035
Ni: allows the residual content ≤ 0.030
Cu: allows the residual content ≤ 0.030
3. 20CrMn delivery state: by heat treatment (normalizing, annealing or tempering) or not to heat treatment delivery, delivery status should be indicated in the contract.
