Material Overview
Hastelloy X (UNS N06002) is a nickel-chromium-iron-molybdenum alloy recognized as one of the most versatile solid-solution strengthened superalloys available globally. This alloy maintains exceptional oxidation resistance at temperatures up to 1200°C and offers outstanding high-temperature strength and stress-rupture properties above 790°C. It is particularly valued for its excellent resistance to carburizing and nitriding atmospheres, making it a preferred material for extreme environment applications across aerospace, industrial heating, and power generation industries.
Chemical Composition
The chemical composition of Hastelloy X is carefully balanced to deliver its signature high-temperature performance, creating a robust austenitic matrix that maintains structural integrity under thermal stress.

Manufacturing Process
- Melting Practice: High-quality Hastelloy X is produced using Vacuum Induction Melting (VIM) followed by Electroslag Remelting (ESR) or Vacuum Arc Remelting (VAR)
- Hot Working: Ingots are forged or hot-rolled at 1150°C to 1000°C into round bars with controlled deformation processes
- Heat Treatment: Solution annealing at 1150°C to 1180°C followed by rapid cooling for optimal microstructure
- Surface Finishing: Turning and polishing for bright bars to achieve superior surface finish with precise dimensional tolerances
Key Features and Advantages
- Exceptional high-temperature strength up to 1200°C with impressive creep resistance
- Outstanding oxidation resistance in both oxidizing and reducing environments
- Excellent corrosion resistance to hot sulfur-bearing gases, carburizing atmospheres, and combustion products
- Good fabrication characteristics with excellent weldability using common techniques
Applications
- Aerospace Industry: Jet engine combustion chambers, flame holders, afterburner components
- Industrial Gas Turbines: Combustion liners, transition ducts, nozzle rings
- Heat Treatment Equipment: Radiation tubes, retorts, muffles, furnace rolls
- Power Generation: Nuclear reactor components, superheater supports, boiler components
- Chemical Processing: Pyrolysis tubes, reformer components, high-temperature reactors
Quality Assurance
When sourcing Hastelloy X round bars, work with qualified suppliers who provide full material traceability, including chemical certification and heat treatment records, to ensure compliance with required specifications and end-use application requirements.
