AISI Matte Stainless Steel Sheet Plate 304 304l Mirror Finished

As stainless steel has many ideal properties required by building materials, it can be said to be unique among metals, and its development continues. In order to make stainless steel perform better in traditional applications, the existing types have been improved, and in order to meet the strict requirements of advanced construction applications, new stainless steels are being developed. Due to continuous improvement in production efficiency and continuous improvement in quality, stainless steel has become one of the most cost-effective materials chosen by architects. Stainless steel combines performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.Austenitic stainless steel generally belongs to corrosion-resistant steel and is the most widely used type of steel. Among them, 18-8 stainless steel is the most representative. It has good mechanical properties and is convenient for machining, stamping and welding. It has excellent corrosion resistance and good heat resistance in oxidizing environment. But it is particularly sensitive to the medium containing chloride ions (CL-) in the solution and is prone to stress corrosion. 18-8 stainless steel is divided into three grades according to the carbon content in its chemical composition: general carbon content (Wc≤0.15%), low carbon grade (Wc≤0.08%) and ultra-low carbon grade (Wc≤0.03%) ). For example, the three steel plates 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr17Ni14M02 in my country's national standards belong to the above three grades. Many countries in the world feel the shortage of nickel reserves. In order to save nickel, as early as the 1940s and 1950s, the world began to use manganese and nitrogen to replace part of the nickel in 18-8 stainless steel. The steel plates developed and listed in the national standards include 1Cr17Mn6Ni5N and 0Cr19Ni9N.
