301 stainless steel exhibits significant work hardening during deformation and is used in a variety of applications where higher strength is required.
302 stainless steel is essentially a variant of 304 stainless steel with a higher carbon content, which gives it a higher strength by cold rolling.
302B is a stainless steel with a high silicon content, which has high resistance to high temperature oxidation.
303 and 303Se are free-cutting stainless steels containing sulfur and selenium, respectively, for applications where the main requirements are easy cutting and high gloss.
303Se stainless steel is also used to make parts that require enthusiasm, because under these conditions, the stainless steel has good hot workability.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).
304L is a variant of 304 stainless steel with a lower carbon content for applications requiring soldering. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may result in intergranular corrosion (weld erosion) in certain environments.
304N is a nitrogen-containing stainless steel added to increase the strength of the steel.
305 and 384 stainless steels contain high nickel and have a low work hardening rate, making them suitable for a variety of applications where high cold formability is required.
308 stainless steel is used to make the electrode.
The nickel and chromium contents of 309, 310, 314 and 330 stainless steel are relatively high in order to improve the oxidation resistance and creep strength of steel at high temperatures. The 309S and 310S are variants of the 309 and 310 stainless steels, except for the lower carbon content, in order to minimize the carbides precipitated near the weld. 330 stainless steel has a particularly high resistance to carburizing and thermal shock resistance.
Types 316 and 317 stainless steel contain aluminum and are therefore significantly more resistant to pitting corrosion in marine and chemical industrial environments than 304 stainless steel. Among them, variants of Type 316 stainless steel include low carbon stainless steel 316L, nitrogen-containing high-strength stainless steel 316N, and high-sulfur free-cutting stainless steel 316F.
321 , 347 and 348 are stainless steel stabilized by titanium, niobium and tantalum, respectively, and are suitable for use as welded members at high temperatures. 348 is a stainless steel suitable for the nuclear power industry, which has certain restrictions on the combination of bismuth and cobalt.
