Applications & Benefits
Why this grade
Hastelloy X is a high-temperature alloy rather than a wet-corrosion one. It holds oxidation resistance to around 1200°C and is equally at home in reducing, carburising and oxidising furnace atmospheres, which is why it has long been the choice for gas turbine combustors, transition ducts and industrial furnace hardware.
- Gas turbine engine components: combustor cans, transition ducts, spray bars, flame holders
- Industrial furnace rolls, retorts, muffles, and heating elements
- Chemical processing reactors, heat exchangers, and piping in oxidizing environments
- Aerospace: jet engine components requiring high strength and oxidation resistance
- Oil & gas: refinery equipment and components exposed to high temperature and corrosive atmospheres
- Power generation components facing thermal and chemical exposure
