So far, stainless steel has a history of more than a hundred years. In accordance with the product structure, stainless steel can be divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel; in accordance with the chemical composition, steel can be divided into chrome stainless steel, nickel stainless steel. Stainless steel rust-proof mechanism is mainly based on the addition of a large number of chromium elements: on the one hand, because chromium makes the electrode potential of iron chromium alloy steel increased, especially when the chromium content of 1/8, 2/8, 3/8... atomic ratio, iron - chromium alloy steel electrode potential was leaping increase; on the other hand, in the corrosive medium, the chromium element can make the surface of stainless steel to produce a layer of solid and dense oxide film, thereby inhibiting further corrosion.
Stainless steel for its good corrosion resistance, high temperature and other characteristics is widely used in tableware, white goods, chemicals, energy, transportation and aerospace and other fields, including tableware, white areas of stainless steel consumption accounted for about 45% 19% of decoration, 16% of manufacturing, 12% of chemical energy, and about 7% of transportation; and the lower reaches of Pu mainly concentrated in the construction, machinery manufacturing and automotive manufacturing. In contrast, stainless steel demand side had more diversified dispersion.
In the first half of 2016, the national stainless steel production is estimated to increase by 9.17%.
