28 austenitic stainless steel 0Cr18Ni9.
Stainless steel with austenitic stainless steel at room temperature. The steel contains about 18% Cr, 8%~10% Ni, C about 0.1%, with a stable austenite structure. Austenitic chromium nickel stainless steel including the famous 18Cr-8Ni steel and on this basis to increase the content of Cr and Ni and join Mo, Cu, Si, Nb, Ti and other elements of the development of high Cr-Ni series steel. Austenitic stainless steel is not magnetic and has high toughness and plasticity, but the strength is low, it is not possible to strengthen through the phase transformation, only through the cold processing to strengthen. Such as the addition of Ca, S, Se, Te and other elements, it has a good machinability. This kind of steel in addition to the resistance to oxidation of acid corrosion, if it contains Mo, Cu and other elements can also be resistant to sulfuric acid, phosphoric acid, and formic acid, acetic acid, urea, etc.. If the carbon content in the steel is less than 0.03% or Ti and Ni, the corrosion resistance of the steel can be improved significantly. High silicon austenitic stainless steel concentrated nitric acid is willing to have a good corrosion resistance. As the austenitic stainless steel has comprehensive and good comprehensive performance, in all walks of life to obtain a wide range of applications.
