Description
Alloy 825 (Incoloy 825® UNS N08825 Werkstoff Nr. 2.4858) is a nickel-iron-chromium-molybdenum alloy with good corrosion resistance to sulfuric and phosphoric acids and sea water. It is similar to alloy 800 but with improved resistance to aqueous corrosion. Although not fully resistant to stress-corrosion cracking in boiling magnesium chloride, alloy 825 has good resistance in neutral chloride media.
Applications
pickling hooks and equipment,
pickling-tank heater, phosphoric acid evaporators,
chemical process equipment,
tank trucks, propeller shafts,
spent nuclear fuel element recovery
