Difference Between Galvanized Steel and Stainless Steel

Jun 29, 2022

Galvanized steel sheet

Galvanized steel plate is coated with a layer of metallic zinc on the surface of the steel plate to prevent the surface of the steel plate from corroding and prolong its service life. This galvanized sheet is called galvanized sheet. Galvanized steel strip products are mainly used in construction, light industry, automotive, agriculture, animal husbandry, fishing and commerce. Among them, the construction industry is mainly used to manufacture roof panels, roof grilles, etc. for anti-corrosion industries and civil buildings. It is used in light industry to manufacture housings of household appliances, civil chimneys, kitchen utensils, etc., while the automobile industry is mainly used to manufacture corrosion-resistant parts of automobiles; agriculture, animal husbandry and fishery are mainly used for storage and transportation of food, and refrigeration processing equipment for meat and aquatic products. etc.; Commercial is mainly used for storage and transportation of materials, packaging equipment, etc.


Galvanized steel sheets are available in a variety of sizes, contact us for exact pricing. We supplies high quality galvanized plates of various sizes and grades. Get a quote.


Stainless steel sheet

Stainless steel refers to steels that are resistant to weakly 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, the steel that is resistant to weak medium corrosion is usually called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid-resistant steel. Stainless steel is usually divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, etc. In addition, it can also be divided into: chromium stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel, etc. The corrosion resistance of stainless steel decreases with increasing carbon content. Therefore, most stainless steels have a low carbon content, usually no more than 1.2%, and some steels have a Wc (carbon content) even less than 0.03% (eg 00Cr12). The main alloying element in stainless steel is Cr (chromium). Steel has corrosion resistance only when the Cr content reaches a certain value. 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.
