N08825 ASME SB 425 Incoloy 825 Iron Chromium Alloy

• Inconel Alloy Series

Incoloy 825 Alloy is an all-purpose project alloy, have good corrosion resistance of the acid and alkali metal property in both oxidation and reduction environments. High nickel content made it with effective stress corrosion cracking resistance performance. Incoloy 825 have excellent corrosion resistance in different kinds of media, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide, and hydrochloric acid. A variety of media corrosion of nuclear-burning dissolver show Incoloy 825 high integrated prpperty, like sulfuric acid, nitric acid and potassium hydroxide are all dealing in a same device.

Features:
1. Good stress corrosion cracking resistance performance
2. Good resistance for pitting and crevice corrosion performance
3. Good anti-oxidation and non-oxidzing heat acid performance
4. Good mechanical performance in both room temperature and up to 550°C
5. Have the pressure vessel authenticate when manufacture temperature up to 450°C

Applications:
Incoloy 825 Alloy widely use in many kinds of industry field that the working temperature no more than 550°C
1. Sulfuric acid factory usage for heating pipe, container, basket,chain and so on
2. Cooling heat exchanger, marine product pipeline system and gas pipeline of acidic environment
3. Heat exchanger, steam machine, washing, impregnation pipe, etc. for phosphoric acid produce
4. Oil refining in the air heat exchanger
5. Food project
6. Chemical process
7. Application of high pressure oxygen flam-retardant alloy
