17-4PH stainless steel project 70 stainless steel customization 630 (17Cr-4Ni) in traditional 630 (17Cr-4Ni)? On this basis, the steering performance is improved. The alloy is an alloy stainless steel hardened by martensite precipitation/aging, which has high strength and hardness and excellent corrosion resistance. It has good processability and can be age hardened by one-time low temperature treatment.

The chemical composition of 17-4PH is as follows:

The welding materials and welding process of 17-4PH precipitation hardening stainless steel are as follows:
