The corrosion resistance of all kinds stainless steel
Issuer:Huanyulongfei Issue time:2008-10-7 Read£º259 times
304 is a versatile stainless steel, widely used in the production requirements of good performance (forming and corrosion resistance) and mechanical equipment.
301 stainless steel in the deformation, when shown a marked hardening, was asked for to be used in a higher intensity of occasions.
302 stainless steel is a kind of higher carbon content of 304 stainless steel, so that it can be cold-rolled to be the higher intensity performance.
302B is a kind of high silicon content of stainless steel, which has a high temperature anti-oxidation.
303 and 303Se respectively contain sulfur and selenium, they are easy cutting stainless steel, the main requirements for the cutting table and Finish high places. 303Se for the production of stainless steel need to be hot headed, because in such conditions, this stainless steel has a good hot-processing.
304L is a low-carbon stainless steel of 304, to be used for welding occasion. Lower carbon content makes minimum carbide while welding in the heat affected zone, and carbide precipitation could lead to stainless steel in certain circumstances arising from intergranular corrosion (weld erosion).
304N is a nitrogen-containing stainless steel, the increase of nitrogen in order to increase the strength of steel.
305 and 384 stainless steel with high nickel, their low rate of work hardening, suitable for cold forming of a variety of occasions demanding.
308 for the production of stainless steel welding rod.
309,310,314 and 330 stainless steel contain higher of nickel and chromium, in order to improve the steel under high temperature anti-oxidation and creep strength. 305s and the 310S are and variants of 309 and 310 stainless steel, their carbon content is low in order to make the weld in the vicinity of carbide precipitation to a minimum. 330 stainless steel has a particularly high anti-carburizing and thermal shock resistance.
316 and 317 stainless steel contain aluminum, which in the marine and chemical industry point of anti-corrosion significantly better than stainless steel 304, 316 stainless steel include 316L, 316 N and 316F.
321,347 and 348 respectively to titanium, niobium and tantalum, niobium and stability of stainless steel, suitable for high temperature components used in welding. 348 is applicable to a nuclear power industry, stainless steel, and tantalum together Drilling of a certain amount.
