NS111

NS111 (N08825, 2.4858) alloy is a titanium-stabilized all-austenitic nickel-iron-chromium alloy with the addition of copper and molybdenum. 1, NS111 (N08825, 2.4858 alloy has the following characteristics. (1) Good resistance to stress corrosion cracking. (2), good resistance to pitting and crevice corrosion (3), good resistance to oxidation and non-oxidative thermal acidity (4), good mechanical properties at room temperature and up to 550°C (5), certification for manufacturing pressure vessels at temperatures below 450°C

NS111 application areas. Excellent stress corrosion resistance in water containing chlorides and low concentration of NAOH, the party is widely used in the manufacture of stress corrosion resistant equipment, instead of 18-8 austenitic steel, in the power industry for pressure water reactor evaporator, high temperature gas-cooled reactor, sodium-cooled fast reactor heat exchanger and superheated steam tubes. In the chemical industry for HNO3 cooler, acetic anhydride cracking tube and a variety of heat transfer equipment.
