30CrMnSiA in the carbon, high strength, poor welding performance. 30CrMnSiA quenched and tempered after a high strength and sufficient toughness, hardenability Ye Hao. After quenching and tempering the material to do the wheel shaft, gear, sprocket can be. 30CrMnSiA has good processability, processing deformation is small, anti-fatigue performance is quite good. For shafts, piston parts and other spare parts. For cars, aircraft, a variety of special wear-resistant parts and so on.
It is high strength, but in the carbon quenched and tempered steel, with a large hardenability, so poor welding performance.
The material after quenching has a high strength and sufficient toughness, hardenability Ye Hao. After quenching and tempering the material to do the wheel shaft, gear, sprocket can be. If you do the tool, roughing into a tool shape. Conditioning treatment. Grinding the edge with a carbide cutter and polishing the polishing machine. Surface roughness of 3.2 should be no problem. The material color is darker, galvanized is not for a beautiful, but also rust.
