| 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. |
