Hastelloy X Round Bar UNS N06002 Bars with High-Temperature Strength and Corrosion Resistance for Custom Cutting Any Length
Hastelloy X (UNS N06002/Alloy X) is a nickel-chromium-iron-molybdenum alloy engineered for extreme temperature and corrosive environments. This solid solution strengthened nickel-base superalloy delivers exceptional oxidation resistance and high-temperature strength, making it ideal for aerospace, industrial furnace, and chemical processing applications.
Our Hastelloy X round bars maintain excellent strength in oxidizing atmospheres up to 1200°C (2200°F) and in reducing atmospheres up to 980°C (1800°F), with outstanding resistance to sulfidation, carburization, and other high-temperature degradation processes.

Hastelloy X retains significant strength at elevated temperatures, with tensile strength of approximately 310 MPa at 815°C, making it suitable for high-stress applications in extreme environments.
- Aerospace Industry: Combustion chamber components, flame holders, transition ducts, turbine casings, and afterburner parts for jet engines
- Industrial Gas Turbines: Burner cans, transition pieces, flame tubes, nozzle rings, and structural components
- Industrial Furnaces: Radiation tubes, furnace rolls, retorts, internal supports, hot air ducts, and burner nozzles
- Chemical Processing: High-temperature reactor components, heat exchanger tubing, pyrolysis tubes, reformer tubes, and fixture materials
Hastelloy X exhibits good machinability in the solution annealed condition using conventional methods. The alloy can be cold formed using standard techniques, with intermediate annealing recommended for severe deformation.
Hastelloy X offers excellent welding characteristics and can be readily joined using GTAW/TIG, GMAW/MIG, and SMAW methods. Matching filler metals such as HHastelloyX or HGH3113 welding wire are recommended.
Optimal properties are achieved through solution treatment at 1175°C ±15°C followed by rapid cooling. For stress relief after machining or welding, heat treatment at 870°C ±10°C for 30-60 minutes with air cooling is recommended.
