What is the difference between galvanized sheet and stainless steel

Stainless steel does not need corrosion protection, iron will be corroded. In short, the zinc on the surface will fall off after a long time. The cold plating and hot plating of galvanized sheet refers to coating a layer of metallic zinc on the iron sheet for anticorrosion. Of course, the price is expensive. The difference between galvanized sheet and stainless steel? Galvanized steel sheet is used to prevent corrosion on the surface of the steel sheet and prolong its service life. A layer of metallic zinc is plated on the surface of the steel sheet, which is called galvanized sheet. Galvanized steel strip products are mainly used in construction, light industry, automobiles, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used for the manufacture of anticorrosive industrial and civil building roof panels, roof trusses, etc. Light industry uses it to manufacture appliance shells, civil chimneys, kitchen utensils, etc.

The automobile industry is mainly used to manufacture corrosion-resistant parts of automobiles. Agriculture and animal husbandry are mainly used for grain storage and transportation, meat and aquatic products freezing processing equipment, etc. Mainly used for material storage and transportation, packaging equipment, etc. Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemical corrosive media such as acid, alkali, and salt. It is also called stainless steel and acid-resistant steel. In practical applications, steel corroded by weak corrosive media is often called stainless steel, and steel resistant to chemical media corrosion is called acid-resistant steel. Stainless steel is generally divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel. In addition, it can be divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel. As the carbon content increases, the corrosion resistance of stainless steel decreases. Therefore, the carbon content of most stainless steels is less than 1.2 points, and the Wc (carbon content) of some steels is even less than 0.03 points (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a chromium (chromium) content of at least 10.5 points. Stainless steel also contains elements such as nickel, titanium, manganese, nitrogen, niobium, molybdenum, and silicon. Stainless steel is not prone to corrosion, pitting, rust or wear. Stainless steel is also one of the strongest metal materials for construction. Because stainless steel has good corrosion resistance, it can make the structural components yongjiu maintain the integrity of the engineering design. Chromium-containing stainless steel also combines mechanical strength and high ductility, is easy to manufacture, and can meet the needs of architects and structural designers.
