Galvanized sheet differs from stainless steel

Galvanized steel plate is to prevent the surface of the steel plate from corrosion, prolong its service life, coated with a layer of metal zinc on the surface of the steel plate, this coated thin steel plate is called galvanized plate.

Galvanized sheet and strip products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for manufacturing anti-corrosion industrial and civil building roof panels, roof grilles, etc. The light industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc., and the automobile industry mainly uses it to manufacture corrosion-resistant parts of cars, etc. Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, frozen processing tools for meat and aquatic products, etc. Commercial mainly used as materials storage and transportation, packaging appliances.

Stainless steel refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, and the steel with chemical corrosion resistance is called acid resistant steel.

Stainless steel is often divided into: martensitic steel, ferrite steel, austenitic steel, austenitic - ferrite (duplex) stainless steel and precipitation hardening stainless steel. In addition, can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel.

The corrosion resistance of stainless steel decreases with the increase of carbon content, therefore, the carbon content of most stainless steel is low, the maximum is not more than 1.2%, some steel Wc (carbon content) even lower than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (Chromium), and only when Cr content reaches a certain value, steel has corrosion resistance. Therefore, stainless steel Cr (chromium) content is generally at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si and other elements.

Stainless steel is not prone to corrosion, pitting, rust or wear. Stainless steel is also one of the strongest metal materials used in construction. Due to its excellent corrosion resistance, stainless steel enables structural components to maintain permanent engineering design integrity. Chromium-containing stainless steel also combines mechanical strength and high extensibility, making it easy to manufacture components and satisfying the needs of architects and structural designers.
