Stainless Steel and Heatproof Steel Character and Usage

Grade	Approx Components	Properties and Use
SUS 304	18Cr-8Ni	Stainless steel and heatproof steel are the most popular steel categories for food container, general chemical equipment and atomic equipment.
SUS 304L	18Cr-9Ni	304 is an extremely low carbon steel featured of resistance to grain boundary corrosion, for the parts free of heat treatment after welding.
SUS 310S	25Cr-20Ni-0.06C	Resistance to repeating heating below 1035℃ and oxidization resistance superior than 309S, applicable to materials for heating furnace as well as purification devise for auto exhaust and so forth.
SUS 316	18Cr-12Ni-2.5Mo-0.06C	High temp. creep, high rupture strength, suitable for parts for heat exchange device, high-temperature-corrosion-resistant bolt and so on.
SUS 317	18Cr-12Ni-3.5Mo-0.06C	High temp. creep, high rupture strength, suitable for parts for heat exchange device.
SUS 321	18Cr-9Ni-Ti-0.06C	Applicable to the parts under the 400℃~900℃ corrosion condition and high temp. soldering material.
SUS 409	11Cr-Ti-0.06C	Suitable for purification devise for auto exhaust and muffler
SUS 410	13Cr	Good corrosion resistance and mechanical process capability, suitable for general usage and knife product.
SUS 420J1	13Cr-0.2C	Quench status with high hardness, corrosion resistance stronger than 13Cr, suitable for turbo blade.
SUS 420J2S	13Cr-0.3C	Harder than 420J2 after quench, suitable for knife, nozzle, valve base, valve, ruler and so forth.
