Product Description
SUS630 martensitic stainless steel is characterized by high hardness, high strength and corrosion resistance. In particular, precipitated hardness martensitic stainless steels are the hardest of all types of stainless steels. After heat treatment, the mechanical properties of steel are more perfect, can reach the strength of 1100-1300mpa, this grade can not be used for high 300℃ or very low temperature, SUS630 has good corrosion resistance to the atmosphere and dilute acid or salt, the corrosion resistance of the steel is the same as 304 and 430. At present, it is widely used in high strength parts with certain corrosion resistance requirements in valve, shaft and chemical fiber industry.

SUS630 stainless steel plate Uses:
1.SUS630 stainless steel plate is suitable for the production of high corrosion resistance, high wear resistance of plastic mold and rubber mold;
2.SUS630 stainless steel module is suitable for the manufacture of semiconductor IC sealing plastic mold and mold parts requiring corrosion and rust resistance;
3.SUS630 stainless steel round rod is suitable for turbine blade, nozzle, valve, plate ruler and high corrosion resistance bearing parts, high wear resistance equipment parts;
4.SUS630 stainless steel is suitable for the production of food industry, offshore platform and other high corrosion resistant mold equipment.
Due to its good mechanical properties and corrosion resistance, SUS630 is also widely used in petrochemical, nuclear power, aerospace and military industry, shipbuilding, automobile, medical and other industries.
