1.\u00a0<\/span><\/strong>Introduction to 30CrMnSiA materials<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 30CrMnSiA is medium carbon, with high strength and poor welding performance. After tempering, 30CrMnSiA has high strength and sufficient toughness, and has good hardenability. After conditioning, the material can be made of grinding wheel shaft, gear, and sprocket. 30CrMnSiA has good processing properties, small processing deformation, and good fatigue resistance. Used for shafts, piston accessories, etc. Used for various special wear-resistant parts and accessories of cars and aircraft.<\/span><\/p>\n
