High strength Incoloy alloys, including Incoloy 800 and Incoloy 825, are highly sought after due to their ability to resist both oxidization and carbonization in high-temperature settings.
Nickel-based 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).
Corrosion resistant Incoloy alloy 825 steel material available forms include seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges like inconel 825 plate, inconel 825 erw pipes, inconel 825 flange, inconel 825 cap, inconel 825 elbow, inconel 825 reducer, inconel 825 sheet etc. Also offers uns n08825 flange, alloy 825 fittings, uns n08825 reducer, alloy 825 cap, uns n08825 plate, alloy 825 tube and many more.
