Which is better, stainless steel plate kitchen?
According to the organizational structure of classification at room temperature, a martensitic, Austenitic, Ferritic and duplex stainless steel; according to the classification of the main chemical components, basically can be divided into chromium and chromium nickel stainless steel two systems; by use of minute nitric acid resistant stainless steel, stainless steel, stainless steel corrosion resistance to sulfuric acid and so on, according to the corrosion resistance the type can be divided into stainless steel pitting corrosion, stress corrosion resistant stainless steel, intergranular corrosion resistant stainless steel etc.;
Classification according to functional characteristics can be divided into non-magnetic stainless steel, easy to cut stainless steel, low temperature stainless steel, high strength stainless steel and so on. Because the stainless steel material with excellent corrosion resistance, formability, and compatibility in a wide temperature range, strong toughness characteristics, so get widely used in heavy industry, light industry, supplies industry and construction decoration industry.
Popularly speaking, stainless steel is not easy to rust steel, in fact, part of stainless steel, both rust resistance, but also acid resistance (corrosion resistance). Stainless steel stainless steel and corrosion resistance is on the surface of chromium rich oxide film (film) formation. The rust resistance is relative to that of corrosion resistance. The test shows that the steel in the atmosphere, water and other medium and weak acid oxidizing medium, the corrosion resistance increased with the increase of water content of chromium in steel, when the chromium content reaches a certain percentage, the steel corrosion resistance mutation from rust to rust, corrosion and corrosion resistance to never. There are many classifications of stainless steels.
Commonly used stainless steel materials are: 201, 202, 301, 303, 304L, 316, 316L, 321, 310S, 401, 409, 410, 420J1,, 420J2, 430, 304, 439, 443, and 444.
