BACKGROUND

Incoloy alloy 825 is a nickel, iron, chromium alloy with additions of molybdenum, copper and titanium, with exceptional resistance to many aggressive corrosion environments.

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).

Alloy 825 offers exceptional resistance to corrosion by sulphuric and phosphoric acids and is often the most cost-effective alloy in sulphuric acid service. 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.

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).

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.

Machinability

Incoloy 825 is classed as a ‘C’ alloy and is reasonably easy to machine.

Welding

The alloy is readily weldable by the normal processes (GMAW (MIG), GTAW (TIG), SMAW (manual), SAW). The joint must be clean to avoid contamination of the weld pool.

Welding Consumables

Normal Service Higher Strength Best Corrosion Resistance
Welding electrode Inconel WE 112 Inconel WE 112 Inconel WE 112
Filler metal Inconel FM 625 Inconel FM 625 Inconel FM 625
Flux cored wire Inco Cored 625DH Inco Cored 625DH Inco Cored 625DH

Heat Treatment

Incoloy 825 is stabilise annealed at 940°C. The softest structure is obtained at 980°C. Sections heavier than a sheet, strip and wire should be quenched to avoid sensitisation.
