The Difference Between Galvanized Steel And Stainless Steel
Galvanized Steel Sheet
Galvanized steel sheet is coated with a layer of metallic zinc on the surface of the steel sheet to prevent corrosion of the steel sheet surface and prolong its service life. This kind of zinc-coated thin steel sheet is called galvanized sheet. Galvanized steel strip products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc .; the light industry industry uses it to manufacture household appliance shells, civil chimneys, kitchen appliances, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts of cars ; Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products frozen processing equipment, etc .; commerce is mainly used as storage and transportation of materials, packaging equipment, etc.
Stainless Steel Sheet
Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, water, and chemically aggressive media such as acids, alkalis, and salts. It is also known as stainless acid-resistant steel. In practical applications, steel that is resistant to corrosion by weak media is often called stainless steel, and steel that is resistant to chemical media is called acid-resistant steel. Stainless steel is often divided into martensite steel, ferritic steel, austenitic steel, austenitic-ferrite (dual phase) stainless steel, precipitation hardening stainless steel, etc. In addition, it can be divided into: chromium stainless steel, chromium nickel stainless steel, chromium manganese nitrogen stainless steel and so on. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, generally not more than 1.2%, and the Wc (carbon content) of some steels is even less than 0.03% (such as 00Cr12 ). The main alloy element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, the general Cr (chromium) content of stainless steel is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si and other elements.
