N08810-Nickel-Alloy-Seamless-Pipes

Incoloy 825 Pipe, Alloy 825 Tubing ASTM B163 B423 ASME SB163 SB423 N08825 Tubes Tubing Pipes is a nickel-iron-chromium alloy with additions of molybdenum and copper. Alloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric acids and phosphoric acids. Alloy 825 is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

1. Good stress corrosion cracking resistance in chloride and sour (H2S/Cl-) environments
2. Superior resistance for pitting and crevice corrosion performance better than 316L Stainless Steel
3. Good anti-oxidation and non-oxidzing heat acid performance
4. Good mechanical performance in both room temperature and up to 550℃
5. Have the pressure vessel authenticate when manufacture temperature up to 450℃
6. Very good resistance to corrosion in acidic media such as sulfuric acid
7. Good Weldability

ASTM B163 B423 ASME SB163 SB423 N08825 Tubes Tubing Pipes Application

Alloy 825widely use in many kinds of industry field that the working temperature no more than 550℃. UNS N08825 Typical application field:

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 for crude oil and oil refineries, especially where high concentrations of hydrogen sulphide and chloride are present.
5. Food project
6. Chemical process
7. Application of high pressure oxygen flam-retardant alloy
8. Stainless Steel Reheater Tubes and Superheater Tubes for Boiler

Incoloy 825 Pressure Vessels

UNS N08825 is approved for pressure vessel operating temperatures up to 525°C (AS1210, AS4041), 538°C (ASME Boiler & Pressure Vessel Code, Sections I, III, VIII, IX, Cases 1936, N-188). Brittle phases may form in alloy 825 at temperatures above ~ 540°C, so it is not normally used at these temperatures, where creep-rupture properties would be design factors.

Incoloy 825 Pipe, Alloy 825 Tubing Corrosion resistance

Alloy 825 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. 825 have excellent corrosion resistance in different kinds of media, such as sulfuric acidphosphoric acidnitric 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 825 high integrated prpperty, like sulfuric acid, nitric acid and potassium hydroxide are all dealing in a same device.

Alloy 825 General Corrosion

N08825 Nickel Alloy possesses excellent resistance to corrosion. N08825 is far superior to molybdenum alloyed steels such as 316L Stainless Steel, particularly when exposed to non-oxidizing media such as sulfuric acid or phosphoric acid. It also has satisfactory resistance to highly oxidizing agents such as nitric acid. N08825 nickel alloy has significantly better corrosion resistance in formic acid than standard austenitic stainless steel.
