SUS630 is made of copper, niobium /precipitation hardened martensitic stainless steel. Low carbon content, corrosion resistance and weldability are better than the average martensitic stainless steel, similar to the 18-8 stainless steel, heat treatment process is simple, good machinability, high strength, high hardness, good weldability And corrosion resistance. Has been widely used in the promotion of valves, shafts and chemical fiber industry and have a certain corrosion resistance of high-strength components.

SUS630 Features: After heat treatment, the mechanical properties of the product are improved and the compressive strength of up to 1100-1300 Mpa (160-190 ksi) can be achieved. This grade can not be used at temperatures above 300 ° C (572 ° F) or very low temperatures. It has good corrosion resistance to atmospheric and dilute acids or salts, and its corrosion resistance is the same as 304 and 430.
SUS630 Metallography: The organization is characterized by precipitation hardening type.
