GBT 30CrMnSiA Special Alloy Chemical Composition
30CrMnSiA material is Chinese structural steel and alloy steel. After quenching and tempering, 30CrMnSiA has high strength and sufficient toughness, as well as good hardenability. After quenching and tempering, the material can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA has good workability, small deformation, and good fatigue resistance. For shafts, pistons and other parts. It is used for various special wear-resistant parts of automobiles and aircrafts. It is usually delivered in Bright Steel Round Bar condition.
