Quick Details
1: 630 steel introduction
630 stainless steel is martensitic precipitation hardening type stainless steel. Its properties are characterized by easy adjustment of strength grade, which can be adjusted by changing the heat treatment process. Martensite transformation and aging treatment to form precipitation hardening phase are the main strengthening means. 630 stainless steel has good attenuation performance, corrosion fatigue resistance and water drop resistance.
