In the hottest section of a gas turbine—the combustion zone—strength is secondary to survival. The material must resist oxidising into dust.
Layrr Materials Hastelloy X is the premier choice for extreme-temperature environments. Unlike precipitation-hardened alloys (like Inconel 718) which can over-age and lose strength above 700°C, Hastelloy X relies on solid-solution strengthening. It maintains its structural integrity and forms a protective, tenacious oxide scale up to 1200°C (2200°F). We supply this powder specifically for engineers who need a material that is as printable as it is durable.
Hastelloy X is unique because it balances high-temperature strength with exceptional ductility.
Oxidation Shield: The high Chromium (22%) content ensures the formation of a stable oxide layer that protects the underlying matrix from rapid degradation in air or combustion gas.
Solid-Solution Strength: Molybdenum (9%) strengthens the nickel matrix without relying on gamma double prime precipitates. This makes the alloy less sensitive to thermal history and easier to weld/print.
Carbide Stability: Carefully controlled carbon content ensures the formation of carbides that pin grain boundaries, preventing creep deformation.
Because it is solid-solution strengthened, Hastelloy X is significantly more "forgiving" in the additive process than Inconel 718 or 738.
Crack Resistance: The alloy's high ductility makes it highly resistant to strain-age cracking during the rapid solidification of Laser Powder Bed Fusion (LPBF).
Weldability: Excellent response to Directed Energy Deposition (DED) for repairing expensive turbine components.
Layrr Morphology: Our gas-atomized powder features minimal satellite particles, ensuring high packing density and reducing the risk of lack-of-fusion defects in thin-walled combustion liners.
This is the default material for the "hot section" of aerospace and industrial engines:
Aerospace Propulsion: Combustion liners, transition ducts, and flame holders that face direct flame impingement.
Industrial Gas Turbines: Vanes and shrouds requiring long-term oxidation resistance.
Petrochemical: Furnace rolls and chemical processing components resistant to stress-corrosion cracking (SCC).
Nuclear: High-temperature gas-cooled reactor components.
Layrr Technical Note:
While Hastelloy X is highly printable, prolonged exposure to intermediate temperatures (650–870°C) can lead to the precipitation of secondary phases that reduce ductility. A solution annealing heat treatment (1175°C + Rapid Cool) is recommended post-printing to homogenise the grain structure and restore full ductility.
