Introduction
630 stainless steel rod is widely used in high strength parts that require both rust resistance and weak acid, alkali and salt corrosion, such as turbine blades at the end stage, and structural parts that work at a temperature below 300℃ in corrosive environment.
Heat treatment process of SUS630
Heat treatment specification
Solution 1020~1060℃ fast cooling;
2) Aging at 480℃, after solution treatment, air cooling at 470~490℃;
3) Aging at 550℃, after solution treatment, air cooling at 540~560℃;
4) Aging at 580℃, after solution treatment, air cooling at 570~590℃;
5) Aging at 620℃, after solution treatment, air cooling at 610~630℃. Metallographic structure: The microstructure is characterized by precipitation hardening type.
SUS630 is martensitic precipitated hardened stainless steel, with high strength, high hardness, good welding performance and corrosion resistance. It has been widely used in valve, shaft and chemical fiber industry and high strength parts with certain corrosion resistance requirements. SUS630 is martensitic precipitated stainless steel SUS630 special addition of copper precipitated hardening type steel.
SUS630 Stainless Steel (Japan brand)0Cr17Ni4Cu4Nb(China brand) Stainless steel: SUS630 features precipitation hardened steel with added copper. Used for manufacturing shaft and steam turbine components. Precipitation-hardened martensitic stainless steel composed of copper and niobium/columbium has low carbon content, better corrosion resistance and weldability than ordinary martensitic stainless steel, similar to 18-8 stainless steel, with simple heat treatment process and good machinability, but it is difficult to meet the cryogenic processing. Metallographic structure: The microstructure is characterized by precipitation hardening type. Use for manufacturing high corrosion resistance, high strength parts, such as bearings, steam turbine parts. Physical property
