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.
- Chemical: Furnace components, heat exchangers, mixing vessels, gas scrubbers.
- Marine: Turbine housings, seawater pumps, condensers, desalination plants.
- Oil & Gas: Combustor liners, tubing, valve bodies, heat-resistant piping.
- Pharma: Sterilizer parts, reactor internals, cleanroom-compatible hardware.
- Power: Turbine blades, heat recovery systems, high-temp valves & fittings.
- Hardware Supply: Certified, precision-machined bars for OEMs, urgent spares, and high-durability applications.
