Incoloy 825 Plate

Incoloy 825 plate has high corrosion resistance. It contains high nickel content which is sufficient to chloride ion stress corrosion cracking resistance, and a very stable austenite structure.

Alloy 825 plate is enable the alloy to resist reducing agents and acids due to the levels of molybdenum and copper. Chromium provides oxidising resistance to conditions, such as nitrates and oxidising salts and nitric acid solutions. It provides exceptional corrosion resistance by phosphoric and sulphuric acids and it is often the most cost effective alloy in sulphuric acid service.

inconel 825 plate is approved for pressure vessel operating temperatures up to 525°C. At temperatures above ~ 540°C brittle phases may form, so it is usually not used at the temperatures, where creep-rupture properties would be design factors.
alloy 825 sheet has outstanding properties of corrosion resistance. It can resist general corrosion, intergranular corrosion, pitting & crevice corrosion, and stress corrosion cracking in reducing & oxidizing conditions. It can be easily hot or cold worked. It is especially used in phosphoric & sulphuric acids, sulphur containing flue gases, oil wells, sour gas and sea water.

ASTM B424 UNS N08825 hot working should be done in the range of 870 – 1180°C and finishing at 870 – 980°C. Hot worked parts should be stabilized annealed before use

ASME SB 424 UNS N08825 is stabilise annealed at 940°C and the softest structure is obtained at 980°C andit can be easily machined.
