Introduce
UNS N08825 Incoloy 825 is a nickel-iron-chromium alloy that contains small amounts of titanium, copper, and molybdenum. Incoloy® 825’s chemical composition provides great resistance to many corrosive environments, such as pitting, crevice corrosion, intergranular corrosion, and stress- corrosion cracking. Incoloy 825 nickel alloy has good mechanical properties from moderate to high temperatures, with a hot- working range of 1600 to 2150º F. Alloy 825 also maintains good weldability for all conventional processes.
Applications
Nickel alloy UNS N08825 has many different industrial applications, some of which include: Propeller shafts, Phosphoric acid evaporators, Tank trucks, Hot vessels for food, water, sea water, Sulphuric acid piping and vessels, Marine exhaust systems

Weldability
Alloy 825 can be readily welded by the shielded metal-arc process using alloy welding electrode 135, the gas shielded arc processes using alloy filler metal 65, and the resistance welding processes. The alloy requires no postweld heat treatment. The corrosion resistance of deposited weld metal from both covered electrode and bare wire is equivalent to that of the parent metal.
Heat Treatment
Incoloy 825 is stabilise annealed at 940°C. The softest structure is obtained at 980°C. Sections heavier than sheet, strip and wire should be quenched to avoid sensitisation.
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.
Machinability
Incoloy 825 is classed as a ‘C’ alloy, and is reasonably easy to machine.
