SUS630 stainless steel,SUS630 Steel plate
SUS630 is precipitation, quenching, martensite stainless steel, and this level has high strength, hardness (up to 3000 C/5000 C) and corrosion resistance and other characteristics. 630 is a martensitic precipitation hardening, chromium, nickel, copper stainless steel. The steel can be hardened by a single ageing treatment at relatively low temperatures, this minimises any risk of distortion. 630 is an ideal selection when high strength and corrosion is required.
