Description
Products Description
630 stainless steel bar is a martensitic precipitation hardening stainless steel. The performance characteristics of 630 stainless steel are that the strength level can be easily adjusted, which can be adjusted by changing the heat treatment process. The martensitic phase transformation and aging treatment to form precipitation hardening phase are its main strengthening means. 630 stainless steel alloy bar has good attenuation performance, strong corrosion fatigue resistance and water drop resistance.
