What are Hastelloy X Nuts?
UNS N06002 Nuts are matrix-stiffened nickel-chromium-iron-molybdenum alloy fasteners formulated specifically to survive high-temperature combustion atmospheres where conventional stainless steel and standard nickel alloys degrade due to oxidation, carburization, or thermal fatigue.
Manufactured in accordance with ASTM B572 UNS N06002 Nuts standards, this grade incorporates a balanced balance of chromium (20.5% to 23.0%), iron (17.0% to 20.0%), and molybdenum (8.0% to 10.0%). This chemistry creates an adherent, protective oxide film that prevents spalling and degradation in cyclic high-heat applications up to 1200°C.

Why Industries Prefer Hastelloy X Nuts
Aerospace and industrial heating engineers select Hastelloy X Nuts primarily for their combination of oxidation resistance, ease of fabrication, and high creep-rupture strength during continuous exposure to furnace atmospheres.
As a leading Hastelloy X Nuts Supplier, Aurum Overseas supplies precision-machined bolting that resists stress-corrosion cracking in petrochemical reforming operations and avoids the age-hardening embrittlement common in other high-temperature superalloys after prolonged thermal exposure.
Types of Hastelloy X Nuts
Aurum Overseas supplies a comprehensive range of Hastelloy X nut configurations manufactured according to standard DIN, ASME, and ISO dimensional tolerances for multiple engineering assemblies.

Key Advantages of Hastelloy X Nuts
High Oxidation Resistance
Forms a tight chromium-oxide scale that resists oxidation at temperatures up to 1200°C (2200°F).
Carburization and Nitriding Protection
Prevents carbon diffusion and embrittlement in furnace gases and petrochemical reformers.
Thermal Fatigue Resistance
Withstands rapid thermal cycling without cracking or joint loosening.
Good Ductility and Formability
High elongation properties (40%) allow for precision thread forming and secure torque retention.
No Cobalt-Base Price Instability
Provides high-temperature performance comparable to cobalt-base alloys while maintaining a cost-effective nickel-iron matrix.
Key Applications of Hastelloy X Nuts
| Industry Sector | Primary Fastener Application | Key Service Environment |
|---|---|---|
| Aerospace & Gas Turbines | Combustion cans, transition ducts, flame holders | Direct exposure to high-velocity jet fuel combustion gases up to 1200°C |
| Industrial Heat Treating | Retort bolting, furnace baffles, conveyor grid hardware | High-temperature carburizing, nitriding, and inert gas furnace zones |
| Petrochemical Processing | Pyrolysis tubing flanges, reformer furnace internals | High-heat hydrocarbon cracking gases and thermal cycling conditions |
| Nuclear Engineering | High-temperature gas-cooled reactor (HTGR) components | Helium-cooled core structure supports and heat exchange units |
