30 crmnsia carbon, high strength, poor welding performance. After 30 crmnsia quenched and tempered high strength and toughness, enough hardenability. After conditioning, the material spindle gear, chain wheel is ok. 30 crmnsia has good workability, machining deformation of small, anti-fatigue performance is quite good. Used for shaft, piston spare parts, etc. Used in automobile, aircraft, various special wear-resistant parts, et
