For stainless steel,there are following types:
Model 301- has good ductility, used for forming products. Also through mechanical processing to rapid hardening. Welding good. Abrasion resistance and fatigue strength than 304 stainless steel.
Model 302- corrosion resistance with 304, due to the relatively high carbon intensity.
Model 303- by the addition of a small amount of sulfur, phosphorus compared to the 304 more easily cutting.
Model 304- universal model; 18/8 stainless steel. GB brand 0Cr18Ni9.
Model 309- with 304 has better temperature resistance.
Model 316- after the 304, the second most widely used of steel, mainly for the food industry and surgical equipment, adding Mo to obtain a special corrosion resistant structure. Than 304 because of its resistance to chloride corrosion better and thus to "marine steel" to use. SS316 is usually used for nuclear fuel recycling device. 18/10 grade stainless steel is usually in line with the application level.
Model 321- except for the addition of titanium reduces the risk of corrosion of materials other than weld properties similar to 304.
400 series - Ferritic and martensitic stainless steel
Model 408- has good heat resistance, low corrosion resistance, 11% Cr, 8% Ni.
Model 409- is the most inexpensive models (Ying Mei), usually used in automobile exhaust pipe, belonging to the ferritic stainless steel (Ge Gang).
Model 410- martensite (high strength steel), good wear resistance, corrosion resistance is poor.
Model 416- sulfur added to improve the processing properties of materials.
Model 420- - "cutting class" martensitic steel, similar Brinell high chrome the earliest stainless steel. Also used in surgical operation tools, can do very bright.
Model 430- ferritic stainless steel, decorative, such as for car accessories. Good shape, but heat resistance and corrosion resistance is worse.
Model 440- high strength cutting tool steel, carbon slightly higher, after appropriate heat treatment to obtain a higher yield strength, hardness can reach 58HRC, belongs to the most hard stainless steel column. The most common application example is the "razor blade". There are three common models: 440A, 440B, 440C, and 440F (easy processing).
500 series - chromium alloy steel.
600 series - Martensite Precipitation Hardening Stainless steel.
The most common type of 630- precipitation hardening stainless
