TStE380 steel and SA572 Gr.55 steel, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.
