INTRODUCTION . Alloy structural steel is a kind of steel which is used as mechanical parts and various engineering components, whichcontains one or more alloy elements.. 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.
