In addition, SUS630 has good machinability, simple heat treatment, simple welding process, easy manufacturing, but difficult deep cold forming.
The chemical composition of SUS630 includes carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, copper and other elements, among which chromium and nickel have higher content, and the alloying of copper and niobium can improve the strength and corrosion resistance of steel. The physical properties of SUS630 include density, melting point, specific heat capacity, thermal conductivity, linear expansion coefficient, resistivity, longitudinal elastic modulus, magnetism, etc. Its mechanical properties are related to the delivery status, including tensile strength, elongation, elongation, cross-sectional shrinkage, etc.
SUS630 is mainly used for high-strength parts that require rust prevention, resistance to weak acid, alkali, and salt corrosion, such as the last stage moving blades of steam turbines, and structural parts with an operating temperature below 300 degrees Celsius in a corrosive environment. SUS630 has strong resistance to water droplet erosion and can resist the erosion of weak acids, alkalis, and salts. Its material advantages are high strength, good corrosion resistance, and easy processing and manufacturing. Therefore, it has broad application prospects in aerospace, automobile, chemical and other fields. In short, as a martensitic precipitation hardening stainless steel, SUS630 has excellent strength and corrosion resistance and is widely used in the industrial field.
