GB/T 30CrMnSiA Alloy Round Steel Bars

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. 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. It is used in various special wear parts such as automobiles and airplanes.
The material is darker in color and galvanized can add aesthetics and rust.
