30CrMnSiA steel plate is medium carbon steel, with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA steel has high strength, sufficient toughness and good hardenability, and can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA steel plate has excellent machinability, small deformation and good fatigue resistance. It is used for For shafts, pistons and other parts, as well as various special wear-resistant parts of cars and airplanes.
Chemical composition of 30CrMnSiA steel sheet:
Carbon C: 0.28-0.34, Silicon Si: 0.90-1.20, Manganese Mn: 0.80-1.10, Sulfur S: Allowable residual content ≤0.02, Phosphorus P: Allowable residual content ≤0.025, Chromium Cr: 0.80-1.10, Nickel Ni: Allowed Residual content ≤ 0.030, copper Cu: allow residual content ≤ 0.025.
30CrMnSiA steel plate delivery status:
Delivered with heat treatment (normalizing, annealing or high temperature tempering) or no heat treatment, the delivery status should be specified in the contract.
