30CrMnSiA steel plate is medium carbon with high strength and poor welding performance. After tempering, 30CrMnSiA steel plate has high strength, enough toughness and good hardenability. After tempering, the material can be used as grinding wheel shaft, gear and sprocket.
Chemical composition of 30CrMnSiA steel plate: carbon: 0.28-0.34; silicon: 0.90-1.20; manganese: 0.80-1.10; sulfur: allowable residual content ≤ 0.025; phosphorus: allowable residual content ≤ 0.025; chromium: 0.80-1.10; nickel: allowable residual content ≤ 0.030; copper: allowable residual content ≤ 0.025;
30CrMnSiA steel plate has good machinability, small machining deformation and good fatigue resistance. It is used for shaft, piston and other spare parts, as well as various special wear-resistant spare parts of automobile and aircraft.
