Nickel alloys

N08800 • 1.4876 • TPS-Techalloy 800

Datasheet

ALLOY 800 is a nickel-chromium-iron alloy with good resistance to oxidation, retains its strength at elevated temperatures, has good workability and welding properties. Superior to ALLOY 600 in resistance to sulfur, green rot, and cyanid salts, inferior on resistance to nitriding, halogen gases and molten caustics. Excellent corrosion resistance can be expected under oxidizing conditions which are most harmful to ordinary steel and nonferrous metals, good resistance can also be expected in many organic acids and their compounds. Limited resistance may be expected under reducing acid conditions. Applications in calrod units, furnace muffles and heat exchangers.
