Incoloy825 is also known as NS142, UNS N08825, W.NS.2.4858
incoloy825 is a whole austenitic Ni-Cr alloy with iron stabilization treatment, which has good stress corrosion cracking resistance and resistance to spot and seam corrosion, good oxidation resistance and non-oxidation thermal acidity, excellent mechanical properties at room temperature and high temperatures up to 550°C. It is certified to manufacture pressure vessels when up to 450°C. It is widely used in various industrial fields where the temperature does not exceed 550°C. Typical applications are heating tubes, containers, tubes and chains used in sulfuric acid pickling factories, seawater cooling heat exchanger, Marine product pipeline system, acid gas environment pipeline, heat exchanger in phosphoric acid production, evaporator, washing, impregnation pipe and etc., air heat exchanger in petroleum refining, food engineering, chemical process, flame retardant alloy for high-pressure oxygen applications.
