A variety of stainless steel corrosion resistance?
Release date:[2009-8-8]   Review[643]Time

304stainless steel is one kind of universal, which is widely used in production requirements of good comprehensive performance ( corrosion resistance and moldability ) equipment and parts. 301 stainless steel during deformation showing significant work hardening phenomenon, be used to require a higher intensity of various occasions.

302 stainless steel is essentially carbon content is higher304stainless steel variants, through a cold can make its obtain high strength.

302B is a silicon containing high content of stainless steel, it has high resistance to high temperature oxidation property. 303 and 303Se respectively with sulfur and selenium free-cutting stainless steel, used for the main requirements of easy cutting and surface K. ho degrees high occasions. 303Se stainless steel is also used to make need hot upsetting machine, because in this kind of condition, the stainless steel has good heat processing.

304L carbon content is low304stainless steel variants, used to weld occasion. Low carbon content in weld heat affected zone near the precipitated carbide minimized the precipitation of carbide, and may result in stainless steel in some environments of intergranular corrosion ( welding erosion ).

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

In 305and 384stainless steel containing high nickel, its working hardening rate low, suitable for cold forming of high requirements of various occasions.

308 stainless steel for the production of welding rod.

309,310,314and 330 stainless steel nickel, chromium content is higher, in order to improve the steel in high temperature oxidation resistance and creep strength. While 30S5 and310S are 309and 310stainless steel variants, the difference is the low carbon content, as is the adjacent to the welds the precipitated carbide minimized. 330 stainless steel has a particularly high carburizing resistance and thermal shock resistance.

316 and type 317stainless steel containing aluminum, thus in the ocean and chemical industrial environment in anti corrosion ability greatly superior to 304stainless steel. Among them, type 316stainless steel by variants include low carbon stainless steel 316L, nitrogen containing high strength stainless steel316N and sulfur content high stainless steel 316F.

In 321,347and348respectively with titanium, niobium and tantalum, niobium stabilized stainless steel, suitable for use under high temperature welding components. 348 is a suitable for nuclear power industry of stainless steel, tantalum and the drilling of a certain limit.
