Galvanized steel plate is to avoid thick steel plate surface erosion, increase its service life, in the thick steel plate surface coated with a layer of metal material zinc, this kind of zinc coated cold rolled steel plate is called galvanized plate.
Galvanized sheet hot rolled strip commodity is used in engineering construction, light industry, car, agriculture, animal husbandry, fishery and commercial services and other manufacturing industries. In the construction industry is suitable for the production and manufacture of corrosion resistant industrial production and industrial buildings color steel roof, roof Geshan, etc.; The metallurgical industry uses it to produce and manufacture household electrical casing, civilian smoke pipe, kitchen supplies, etc., and the automobile industry is suitable for the production and manufacture of anti-corrosion components of cars, etc.; Agriculture, animal husbandry and fishery key used for grain storage and transportation, meat and seafood refrigerated production and processing supplies; Business services are mainly used for the storage and transportation of supplies, packaging supplies, etc.
Stainless steel plate refers to the corrosion resistance of gas, steam, water and other weak etch substances and acid, alkali, salt and other organic chemical corrosive substances of steel, another name stainless steel acid resistant steel. In specific use, the steel with weak corrosion resistance is often called stainless steel plate, and the steel with solvent resistance is called acid resistant steel.
Stainless steel plate is often divided into: austenitic steel, ferritic steel, ferritic steel, ferritic metallographic structure (duplex) stainless steel plate and set hardbase stainless steel plate, etc. In addition, it can be divided into chromium stainless steel plate, chromium nickel stainless steel plate and chromium manganese nitrogen stainless steel plate.
The corrosion resistance of stainless steel plate decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel plates is low, not more than 1.2%, and the Wc(carbon content) of some steel is even less than 0.03%(such as 00Cr12). The key aluminum alloy element in the stainless steel plate is Cr(chromium), only when the water content of Cr exceeds a certain value, the steel has corrosion resistance. Therefore, stainless steel plate general Cr(chromium) water content is at least 10.5%. Stainless steel plate also has Ni, Ti, Mn, N, Nb, Mo, Si and other elements.
Stainless steel plate is not easy to cause erosion, crevice corrosion, rust or damage. Stainless steel plate is also one of the raw materials with the greatest compressive strength in engineering metal composite materials. Because the stainless steel plate has excellent corrosion resistance, it can make the structural members permanently maintain the consistency of the architectural design. Chromium stainless steel plate also integrates impact toughness and high ductility, which is convenient for the production, processing and manufacturing of components. It can consider the needs of architectural designers and overall design staff.
