What is 630 stainless steel?
630 stainless steel is a martensitic precipitation hardening stainless steel. The performance characteristics of 630 stainless steel are easy to adjust the strength level, which can be adjusted by changing the heat treatment process. Martensite transformation and aging treatment to form a precipitation hardening phase are its main strengthening means. 630 stainless steel has good attenuation performance, strong resistance to corrosion fatigue and water droplets.
