Introduction
Hastelloy X Powder (Alloy X, UNS N06002) is a nickel-based superalloy powder engineered for excellent high-temperature strength, oxidation resistance, and structural stability. Designed for demanding thermal environments, Alloy X maintains mechanical integrity under prolonged exposure to temperatures approaching 1100°C.
In powder form, Hastelloy X is widely used in additive manufacturing (AM), hot isostatic pressing (HIP), and thermal spray applications. Its combination of fabricability, weldability, and resistance to carburization makes it particularly suitable for gas turbine engines, industrial furnaces, and chemical processing systems.
Detailed Description
Alloy X (UNS N06002) is primarily a nickel-chromium-iron-molybdenum alloy with balanced chemistry for oxidation resistance and solid-solution strengthening.
Typical nominal composition (wt%):
Ni: Balance
Cr: ~20–23%
Fe: ~17–20%
Mo: ~8–10%
Co: ~0.5–2.5%
Minor elements: Mn, Si, C (controlled levels)
Spherical Hastelloy X Powder is typically produced by gas atomization, resulting in:
High sphericity for improved flowability
Controlled particle size distribution (PSD)
Low oxygen and impurity content
Uniform internal microstructure
These characteristics are essential for laser powder bed fusion (LPBF), directed energy deposition (DED), and plasma or HVOF thermal spray systems.
The alloy’s strength is derived primarily from solid-solution hardening rather than precipitation strengthening, which enhances its resistance to phase instability during long-term high-temperature service. Hastelloy X also exhibits excellent resistance to oxidation, carburization, and nitriding in combustion environments.
Applications
Hastelloy X Powder is widely used in:
Gas turbine combustor components
Afterburner and transition duct parts
Industrial furnace hardware
Additive manufacturing of high-temperature components
Thermal spray oxidation-resistant coatings
Chemical processing equipment
Aerospace hot-section components
Its ability to withstand thermal cycling and oxidation makes it suitable for parts exposed to continuous heating and cooling cycles.
