200 series - chromium - nickel - manganese austenitic stainless steel

300 series - chromium - nickel austenitic stainless steel

301, good ductility, used for forming products. Can also be machined to rapid hardening. Good weldability. Abrasion resistance and fatigue strength than stainless steel 304.

302 - 304 with corrosion resistance, due to relatively high carbon intensity and therefore better.

303, sulfur, phosphorus by the addition of a small amount compared to the 304 more cutting processing.

304 - general type 18/8 stainless steel. GB 0Cr18Ni9 grade.

309 - 304 better than the heat resistance.

316 - following the 304, the second most widely used of steel, mainly for the food industry and surgical operation equipment, adding Mo to obtain a special corrosion resistant structure. Than 304 because of its resistance to chloride corrosion better so as "marine steel" to use. SS316 is generally used for nuclear fuel recycling device. 18/10 grade stainless steel is usually in line with the application level.
