Stainless steel with austenitic organization at room temperature. When the steel contains about 18% Cr, 8%-10% Ni and about 0.1% C, it has a stable austenitic organization. Austenitic chromium-nickel stainless steel including the famous 18Cr-8Ni steel and on the basis of this increase in Cr, Ni content and the addition of Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series of steel. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but the strength is low, it is not possible to strengthen it through phase transformation, only through cold working for strengthening. Such as the addition of S, Ca, Se, Te and other elements, it has good machinability. This kind of steel in addition to oxidizing acid medium corrosion, if contains Mo, Cu and other elements can also be resistant to sulfuric acid, phosphoric acid and formic acid, acetic acid, urea and other corrosion. Such steel contains less than 0.03% carbon or Ti, Ni, it can significantly improve its resistance to intergranular corrosion performance. High silicon austenitic stainless steel concentrated nitric acid Ken has good corrosion resistance. As austenitic stainless steel has a comprehensive and good overall performance, in all walks of life to obtain a wide range of applications.
