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.
Neeka Tubes can supply this alloy as plate, sheet, strip, bar, rod, wire, tube, pipe, fittings,
fasteners.
