Incoloy 800/800H/800HT Bars and Rods Uses

**Incoloy 800 / 800H / 800HT Bars/Rods** find extensive applications in **heat exchangers, reformer outlet manifolds, furnace components, superheaters, petrochemical piping systems, and nuclear steam generators**. Their resistance to high-temperature oxidation and stress corrosion cracking bestows upon them the suitability for **power plants, thermal processing equipment, and chemical plants**. 800H and 800HT are particularly suitable for **high-temperature pressure vessel parts and heat-treating equipment** because of their improved creep strength. Their resistance to scaling and maintenance of strength in severe thermal and chemical environments makes them a suitable material for long-term high-temperature service conditions.
