Incoloy 825  (similar grade N08825) is an all-austenitic nickel-iron-chromium alloy stabilized by titanium. It is a general engineering alloy with copper and molybdenum added. It is resistant to acid and alkali metal corrosion in both oxidizing and reducing environments. The high nickel content of the alloy makes it effective against stress corrosion cracking. It has good corrosion resistance in various media, such as sulfuric acid, phosphoric acid, nitric acid and organic acids, and alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solutions. Incoloy 825 is widely used in various industrial fields where the operating temperature does not exceed 550°C.

Incoloy825 alloy has the following characteristics:
●Good resistance to stress corrosion cracking.
●Good resistance to pitting and crevice corrosion
●Good oxidation resistance and non-oxidizing thermal acid performance
●It has good mechanical properties at room temperature and high temperature up to 550℃
●Certification for pressure vessels with manufacturing temperature up to 450℃
