Wugang shipping company for 30CrMnSiA related chemical composition, mechanical properties
30CrMnSiA
30CrMnSiA is a carbon medium with high strength and poor weldability. 30CrMnSiA has high strength and good toughness after quenching and tempering, and its hardenability is also good. After quenching and tempering, the material can be used as grinding wheel shaft, gear and chain wheel. 30CrMnSiA has good processability, small deformation and good fatigue resistance. For axle, piston parts and so on. For automobile, aircraft, special wear-resistant parts and so on.

Delivery status
In the case of heat treatment (normalizing, annealing or high temperature tempering) or non thermal treatment, the delivery status shall be indicated in the contract.
It has high strength, but it belongs to medium carbon quenched and tempered steel. It has high hardenability, so its weldability is poor.
The material has high strength and good toughness after quenching and tempering, and its hardenability is good. After quenching and tempering, the material can be used as grinding wheel shaft, gear and chain wheel. If a tool is made, roughing becomes the shape of the tool. Quenching and tempering treatment. Milling edge with carbide cutter, polishing machine polishing. There should be no problem with surface roughness reaching 3.2. The material is darker in color and galvanized, not just for beauty, but also for rust prevention
