Incoloy 825 is highly resistant to corrosion. It has a high nickel content, sufficient to resist chloride ion stress corrosion cracking, and a very stable austenite structure. The levels of molybdenum and copper enable the alloy to resist reducing agents and acids. Chromium gives resistance to oxidising conditions, such as nitric acid solutions, nitrates and oxidising salts. The alloy is titanium stabilised to resist pitting and intergranular attack after fabrication, particularly welding, which includes heating in the critical sensitisation temperature range (650°C - 760°C).

Pressure Vessels

Incoloy 825 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.

Applications of Incoloy 825

Typical Applications of Incoloy Alloy 825 include:

Sulphuric acid piping and vessels
Phosphoric acid evaporators
Pickling tank heaters, pickling tanks and equipment
Chemical process equipment
Propellor shafts
Tank trucks
Calorifiers
Electrostatic precipitator electrodes
Hot vessels for food, water and seawater,
Ammonium sulphate vessels
Expansion bellows
Marine exhaust systems
Power station ash hoppers

Corrosion Resistance

The outstanding property of Incoloy 825 is its corrosion resistance. In reducing & oxidising conditions, Incoloy 825 resists general corrosion, pitting & crevice corrosion, intergranular corrosion and stress corrosion cracking. It is particularly useful in sulphuric & phosphoric acids, sulphur containing flue gases, sour gas and oil wells and sea water.

Fabrication

Incoloy 825 can be readily hot or cold worked. Hot working should be in the range 870 - 1180°C, finishing at 870 - 980°C. For maximum corrosion resistance hot worked parts should be stabilise annealed before use. The alloy is easier to cold form than stainless steels.
