Incoloy Alloy Pipe

Incoloy 825 is a titanium-stabilized fully austenitic nickel-iron-chromium alloy with additions of copper and molybdenum. Incoloy 825 is a general purpose engineering alloy that is resistant to acid and alkali metal corrosion in both oxidizing and reducing environments. The high nickel content makes the alloy 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. The higher comprehensive performance of Incoloy 825 is manifested in nuclear combustion dissolvers with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, which are all processed in the same equipment.

Incoloy 825 material properties

Incoloy 825 is a titanium-stabilized fully austenitic nickel-iron-chromium alloy with additions of copper and molybdenum. Incoloy 825 is a general purpose engineering alloy that is resistant to acid and alkali metal corrosion in both oxidizing and reducing environments.
The high nickel content makes the alloy 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. The higher comprehensive performance of Incoloy 825 is manifested in nuclear combustion dissolvers with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, which are all processed in the same equipment.

Advantage

1.Good resistance to stress corrosion cracking
2.Good resistance to pitting and crevice corrosion
3.Good anti-oxidative and non-oxidative thermal acid properties
4.Good mechanical properties at room temperature and high temperature up to 550℃
5.Approved for pressure vessels with manufacturing temperature up to 450℃

Incoloy 825 material application areas

Incoloy 825 is widely used in various industrial fields where the operating temperature does not exceed 550 ℃.
Typical applications are:
1.Heating pipes, containers, baskets and chains used in sulfuric acid pickling plants.
2.Seawater cooling heat exchanger, marine product piping system, acid gas environment piping.
3.Heat exchangers, evaporators, scrubbers, dip tubes, etc. in phosphoric acid production.
4.Air heat exchanger in petroleum refining
5.Food engineering
6.Chemical process
7.Flame retardant alloy for high pressure oxygen applications
