Stainless materials can be classified into 5 types
Stainless steel, as its name implies, contain quantity of steel. When Cr is added to iron in an amount of about 11% or more, the corrosion resistance of iron is remarkably improved.The Stainless Steel 316 Flanges becomes rust-free especially in air. This is because a thin and dense oxide film with a thickness of several nm called a passive film is formed on the surface of the iron-chromium alloy. This iron-chromium Alloy Steel Fittings of 11%Cr or more is called stainless steel. Stainless steel is roughly classified into a Cr-based alloy with Cr as the main alloying element and a Cr-Ni-based alloy with Ni added in addition to it. Martensite type and Cr-Ni type are divided into austenitic type. In addition, Stainless Steel 316L Flanges having a dual-phase structure of austenite and ferrite, corrosion resistance as stainless steel was retained.The strength was improved by utilizing precipitation hardening.
