304 is a universal stainless steel, which is widely used in the manufacture of equipment and parts requiring good comprehensive properties (corrosion resistance and formability).

301 stainless steel shows obvious work hardening during deformation, which is used in various occasions requiring high strength.

302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content, which can be obtained by cold rolling with higher strength.

302B is a kind of stainless steel with high silicon content, which has high oxidation resistance at high temperature.

303 and 303Se are free cutting stainless steels containing sulfur and selenium, respectively, for applications where free cutting and high light intensity are the main requirements. 303Se stainless steel is also used for machine parts that require hot upsetting because of its good thermal workability under such conditions.

304L is a variant of 304 stainless steel with lower carbon content and is used for welding applications. The lower carbon content minimizes carbides precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.

304N is a stainless steel containing nitrogen, nitrogen is added to improve the strength of steel.

305 and 384 stainless steel contain high nickel, its work hardening rate is low, suitable for a variety of cold molding requirements.

308 stainless steel is used for welding rod.

309, 310, 314 and 330 stainless steel nickel, chromium content is relatively high, in order to improve the oxidation resistance and creep strength of steel at high temperature. While 30S5 and 310S are variants of 309 and 310 stainless steel, the difference is only lower carbon content, in order to reduce the precipitation of carbide near the weld. 330 stainless steel has exceptionally high carburizing resistance and thermal shock resistance.

Type 316 and 317 stainless steels contain aluminum and are therefore significantly superior to 304 stainless steels in pitting corrosion resistance in Marine and chemical industrial environments. Among them, type 316 stainless steel is made up of varieties including low-carbon stainless steel 316L, high strength stainless steel 316N containing nitrogen and free cutting stainless steel 316F with high sulfur content.

321, 347 and 348 are stainless steels stabilized by titanium, niobium plus tantalum, niobium respectively, suitable for high temperature welding members. 348 is a stainless steel suitable for the nuclear power industry, with certain limits on the amount of tantalum and cobalt.
