Classfication Grade Components Characteristics and Application
Austenite SUS201 17Cr-4.5Ni-6Mn-N It saves Ni, and can be regarded as replacement of 301. After cold processing, it gets magnetic, widely used in decoration and kitchenware.
SUS202 18Cr-5Ni-8Mn-N It saves Ni, and can be regarded as replacement of 301. After cold processing, it gets magnetic, widely used in decoration and kitchenware.
SUS301 17Cr-7Ni After cold processing, it get high hardness, it is widely used in Rail vehicles, conveyor, bolts and nuts, spring.
SUS301L 17Cr-7Ni-低C-N It is lower carbon version of 301 stainless steel, and has excellent resistance to intergranular corrosion and welding performance. It is widely used in railways.
SUS301J1 17Cr-7.5Ni-0.1C It has better stretching and bending performance than 304 steel.It is widely used for building, kitchen appliances, devices, buildings, vehicles, etc.
SUS304 18Cr-8Ni It is one of the most widely used stainless steel, and widely used in food production equipment, general chemical equipment, nuclear.
SUS310SSUS309S 25Cr-20Ni22Cr-12Ni Though it has a better corrosion resistance, it is commonly used as heat resistant steel.
It has a better anti-oxidant than 309S, and commonly used as heat resistant steel.
SUS316 18Cr-12Ni-2.5Mo It has a better anti corrosive ability than 304 steel especially in sea water and any medium contains chloride. It is commonly used for anti-pitting.
SUS316L 18Cr-12Ni-2.5Mo-低C It contains less carbon, and has a better inter-granular corrosion resistance.
SUS316N 18Cr-12Ni-2.5Mo-N It add more N in 316 steel, which reduce the yield strength meanwhile increase the hardness. It is an excellent corrosion resistant material with high strength.
SUS317 18Cr-12Ni-3.5Mo It has better pitting corrosion resistance than 316 steel. It is widely used for equipment printing.
SUS317L 18Cr-12Ni-3.5Mo-低C It has very low carbon content and a better inter-granular corrosion resistance.
SUS317LN 18Cr-13Ni-3.5Mo-N-低C Adding more N in 317L, which has higher strength and better corrosion resistance. It is widely used in pressure containers.
SUS317J1 18Cr-16Ni-5Mo It is widely used for liquid chlorine ion exchanger, acetic acid production equipment, production of phosphoric acid and plant bleach equipment.
SUS321 18Cr-9Ni-Ti With Ti added. It has a better inter-granular corrosion resistance, ti can not be used in decoration part.
SUS347 18Cr-9Ni-Nb It contains Nb, and the inter-granular corrosion resistance has been improved.
