Technical characteristics

Incoloy 825 has a high impact hardness at room temperature. It keeps a lasting-quality at cryogenic temperatures. Alloy can be cold-worked and hot-worked. A hot working should be done at +870 — 1180 ° C and should be finished at 870 — 980 °C. Details that are obtained with a hot deformation must undergo a stabilizing annealing before using for providing a maximum of corrosion resistance.

Valves, fittings, flange made of iron-chrome-nickel alloy Incoloy 825 are characterized by a high resistance to corrosion cracking. Alloy is stabilized with titanium and additives of molybdenum and copper. It gives a perfect resistance to effect of aggressive environments including sea water in chemical industry. The only demerit of alloy is its relatively high content (22%) of iron that makes it less resistant to effect of alkaline corrosion. Forged flanges are used in high-pressure vessel, air manifolds, heat-transfer devices. They are used in marine industries such as underwater marine system of oil production, industrial air buffers.


This alloy has a good workability. It can satisfactory be taken to molding. However, it is disposed to a hammering harden. That is why it must be cut at small speeds with a special tool. It differs with an excellent weldability by dint of well-balanced composition. Welding is done without further heat treating or previous heating.


Type Description
without stint
welding is done without further heat treating or previous heating
hardly weldable in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treating (annealing) after welding
limitedly weldable welding is possible at heating to 100−120°С and last heat treating
