Description:
2520 stainless steel is chromium nickel austenite stainless steel has good oxidation resistance, corrosion resistance, due to high percentage of chromium and nickel, having a much better creep strength, can continue to work at high temperatures, has good resistance to high temperature.Nickel (Ni), chromium (Cr) content is high, has good resistance to oxidation 2520 stainless steel , corrosion resistance, acid and alkali resistance, high temperature performance, high temperature resistant steel pipe is dedicated to manufacturing occasions such as the electric heating furnace tubes, stainless steel after the increase of carbon content in austenite size, due to its solid solution strengthening effect strength was improved, the chemical composition of stainless steel austenite size features based on chromium, nickel added, tungsten molybdenum, niobium and titanium elements, due to its organization is face-centered cubic structure, and thus has high strength and creep at high temperature strength.
