      Standards Feature Use
      KS JIS ASRM DIN
      STS 304 SUS 304 TP 304 1.4301 Great corrosion resistance, heat resistance, and low temperature toughness and good formability and weldability. Does not harden by heat treatment and no magnetism. Chemical industrial facility, food industry pipe, car parts, textile industrial facility, heat-resistant parts, ship parts, construction and decoration, kitchen tools, domestic tableware
      STS 304L SUS 304L TP 304L 1.4306 As a low-carbon Ni-Cr steel, it has similar characteristics to 304 in the normal state but has great resistance against integranular corrosion after welding or stress relief heat treatment. Petrochemical industry, chemical fiber industry, nuclear power plant
      STS 316 SUS 316 TP 316 1.4401 Added with Mo and increased Ni, it has great corrosion resistance (especially against sulfuric acid). It has good resistance against pitting corrosion, high creep strength and heat treatment strength. No hardening or magnetism. Petrochemistry, synthetic fiber industry, chemical fertilizer industry, paper industry, food manufacturing industry
      STS 316L SUS 316L TP 316L 1.4404 As a low-carbon Ni-Cr steel containing Mo, it has similar characteristics to 316 but has good integranular causticity after stress relief heat treatment. Paper pulp industry, chemical fiber industry, dying machines, manufacturing equipment for phosphate, etc.
      STS 310S SUS 310S TP 310S 1.4845 Austenite steel type with the highest Cr content, it has improved corrosion resistance by lowering C content. Acetic acid tank, other chemical industrial resistor, etc.
