Incoloy 800HT
Description
Incoloy 800HT is a nickel-iron-chromium alloy designed for long-term use in high-temperature environments like power generation and petrochemical processing. It offers excellent resistance to oxidation, carburization, and sulfidation. This makes it suitable for parts such as radiant tubes, muffles, and heat treatment fixtures. Incoloy 800HT also resists chloride ion stress corrosion cracking and corrosion from organic acids, making it ideal for chemical processing equipment including reactors, distillation units, and piping.
Application：
- Superheater and reheater tubing
- Headers, pigtails, outlet manifolds
- Sheathing for heating elements
- Petrochemical processing
- Power generation
