0.03 - 10mm Standard Incoloy 825 Wire Welding Wire UNS N08825 2.4858 Alloy 825
Incoloy 825 Wires/Wire Rod/Welding Wire (UNS N08825, 2.4858, Alloy 825)
Incoloy 825 is a nickel-iron-chromium super alloy with addition of molybdenum and copper, resisting wide range of corrosive environments and intergranular sensitization.
Incoloy 825 has exceptional resistance to seawater and to reducing chemicals, such as sulfuric and phosphoric acids. Because it is stabilized against sensitization, Incoloy 825 resists intergranular corrosion. This alloy contains sufficient nickel to make it resistant to chloride stress-corrosion cracking. Its molybdenum content provides resistance to pitting. Its chromium content provides resistance to oxidizing media, such as nitric acid, nitrates, and oxidizing salts.
Typical applications include phosphoric acid evaporators, pickling equipment, chemical processing vessels and piping, equipment for recovery of spent nuclear fuel, propeller shafts, tank trucks and so on.
