30CrMnSiA is a medium carbon with high strength and poor welding performance. 30CrMnSiA has high strength and sufficient toughness after quenching and tempering, and hardenability is also good. After quenching and tempering, the material can be used as a grinding wheel shaft, gears and sprockets. 30CrMnSiA has good processability, small processing deformation and good fatigue resistance. For shaft and piston parts and so on. Used in automobiles, aircraft, various special wear-resistant parts, etc.
