APPLICATION AREA:

825 alloy is widely used in various industrial fields where the temperature is not more than 550 °C.

Typical applications for Incoloy 825

  1. Heating pipes, containers, baskets, chains, etc. for sulfuric acid pickling plants.
  2. Seawater cooling heat exchangers, marine product piping systems, acid gas environmental pipelines.
  3. Heat exchangers, evaporators, washing, dip tubes, etc. in the production of phosphoric acid.
  4. Air heat exchanger in petroleum refining
  5. Food Engineering
  6. Chemical process
  7. Flame retardant alloy for high pressure oxygen applications

Incoloy825 UNS N08825 has the following characteristics

  1. Good resistance to stress corrosion cracking
  2. Good resistance to pitting and crevice corrosion
  3. Good oxidation resistance and non-oxidative thermal acid properties
  4. Excellent mechanical properties at room temperature and high temperatures up to 550 ° C
  5. Certification for pressure vessels with a manufacturing temperature of 450 ° C

Corrosion resistance of Incoloy 825

825 alloy is a general-purpose engineering alloy with high acid and alkali corrosion resistance in both oxidizing and reducing environments. Nickel composition makes the alloy effective in stress corrosion cracking resistance. Corrosion resistance is good in various media such as sulfuric acid, phosphoric acid, nitric acid and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid. The higher overall performance of Alloy 825 is manifested in a variety of nuclear combustion dissolvers with corrosive media such as sulfuric acid, nitric acid and sodium hydroxide.
