Applications & Benefits
Why this grade
Incoloy 800 is a 32% nickel, 21% chromium alloy on an iron balance. It is the general-purpose member of the family for heat and corrosion resistance up to about 650°C, and the least expensive of the 800 series. Above that temperature its creep strength falls away and 800H or 800HT applies instead.
- Chemical: Heat exchangers, furnace components, reformers operating in moderately oxidizing atmospheres.
- Marine: Seawater pumps, condensers, piping with moderate corrosion resistance requirements.
- Oil & Gas: Equipment exposed to sour gas with good corrosion resistance and mechanical properties.
- Pharma: Process vessels requiring resistance to heat and corrosion.
- Power: Boilers, superheater tubes, and exhausts needing thermal and oxidation resistance.
- OEM & Fabricators: Ready stock with certifications, ensuring high quality for industrial maintenance and fabrication.
