Incoloy 800/H/HT Wires
Incoloy 800, Incoloy 800H, and Incoloy 800HT are nickel-iron-chromium alloys known for their excellent resistance to high-temperature corrosion and oxidation. They are commonly used in applications that require high-temperature strength and exceptional corrosion resistance.
This Incoloy 800 Wire exhibits an austenite structure similar to austenitic stainless steels, and appropriate heat treatment procedures and requirements are similar. Our Incoloy 800H Wire is often used in Nitric acid catalyst supports, Reformer outlet pigtails and manifolds. Applications of this Incoloy 800HT Electrode include furnace components and equipment, pigtails and headers, sheathing for electrical heating elements and petrochemical furnace cracker tubes. In the solution annealed condition, our Incoloy 800 Coil Wire has superior creep and stress rupture properties. The chemical balance allows this Incoloy 800H Wire to exhibit excellent resistance to oxidation, carburization and nitriding atmospheres. Incoloy 800HT Welding Filler is best joined / welded using products for high temperature situations and resistance to aqueous corrosion at moderate temperatures. Our Incoloy 800 Filler Wire is extremely functional as it maintains a stable structure, even when exposed to high temperature. In addition to the chemistry restrictions, this Incoloy 800H Coil Wire receives a high temperature annealing treatment that produces an average grain size or coarser. Our Incoloy 800HT Welding Electrode is an iron – nickel – chromium alloy having sufficient resistance to carburization and oxidation at high temperatures as well as moderate strength.
