Product information

Brand: SUS444
Standard: JIS G4303/G4311/G4305
‌SUS444 stainless steel is a highly corrosion-resistant ferritic stainless steel with a wide range of applications. ‌ It is especially suitable for water treatment units, heat exchangers, food processing equipment, water heater tanks, water storage tanks and solar energy collection panels ‌.
SUS444 stainless steel has excellent resistance to pitting, crevice corrosion and stress corrosion, and its corrosion resistance is even better than SUS304 and SUS316 in some areas. It performs well in chlorinated and acidic environments and is particularly suitable for use in chemical equipment, pipelines and storage tanks ‌.
In addition, SUS444 stainless steel has high thermal conductivity and small thermal expansion coefficient, which is suitable for use under conditions of thermal cycling. Its yield strength is equivalent to 1.5 times that of carbon steel and 6 times that of fiberglass steel. It has excellent shock resistance, snow resistance, wind pressure resistance and impact resistance ‌.
In summary, SUS444 stainless steel is widely used in industrial and civil fields ‌ because of its excellent corrosion resistance and high temperature properties, as well as good mechanical properties.
