Austenitic stainless steel elbow has good overall performance

by:Mayer     2021-08-17
Austenitic stainless steel elbow refers to stainless steel with austenitic structure at room temperature. When the steel contains about 18% Cr, 8%~10% Ni, and about 0.1% C, the elbow has a stable austenitic structure. Austenitic chromium-nickel stainless steel includes 18Cr-8Ni steel and high Cr-Ni series steel developed by adding Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements on this basis. The austenitic stainless steel elbow is non-magnetic and has high toughness and plasticity, but the strength is low, and it is impossible to strengthen it through phase transformation. It can only be strengthened by cold working. If elements such as S, Ca, Se, Te are added, it has Good machinability. In addition to resistance to oxidizing acid media corrosion, this type of steel can also be resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu. If the carbon content in the austenitic stainless steel elbow is less than 0.03% or contains Ti and Ni, its resistance to intergranular corrosion can be significantly improved. High-silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid. Because the austenitic stainless steel elbow has a comprehensive and good comprehensive performance, it has been widely used in various industries.
