Corrosion-resistant Properties Of Stainless Steel Material

Dec 19, 2016

304 is a universal stainless steel, which is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts.

301 stainless steel showed in the deformation of work hardening, high strength for a variety of occasions.

302 stainless steel is essentially high carbon content 304 stainless steel variants, by cold rolling to give it more strength.

302B is a stainless steel with high silicon content, it has a higher resistance to high temperature oxidation.

303 and 303Se is free cutting stainless steel containing sulfur and selenium, respectively, for major requires cutting and surface finish of the occasion. 303Se stainless steel is also used for making hot upsetting parts, because in such conditions, which has good thermal processing of stainless steel.

304L is a variant of 304 stainless steel with low carbon content, used for welding applications. Lower carbon content makes it near the carbide precipitation in weld heat-affected zone to a minimum, and carbides can cause stainless steel intergranular corrosion in some environments (welding erosion).

304N is a nitrogen-containing stainless steels, nitrogen-enriched is to enhance the strength of steel.

305 and 384 stainless steel containing high levels of nickel, its low rate of work hardening, suitable for various occasions which require high cold formability.

308 stainless steel for the production of welding electrodes.

309, 310, 314 and 330 stainless steel, nickel and chromium content is relatively high, in order to increase the oxidation resistance at high temperature and creep strength. And 30S5 and 310S is 309 and 310 varieties of stainless steel, the difference is lower carbon content, so that the carbide precipitation near the weld to a minimum. 330 stainless steel has a particularly high degree of carburization resistance and thermal shock resistance.
