Key Advantages
High-Temperature Oxidation Resistance
Forms a tight, protective oxide scale that resists spalling and degradation in continuous combustion atmospheres up to 1200°C.
Carburization & Nitriding Defense
Balanced iron, chromium, and nickel composition provides excellent resistance to carbon and nitrogen absorption in industrial heat-treat atmospheres.
Creep & Stress-Rupture Strength
Maintains structural joint integrity under prolonged high-stress, high-temperature thermal exposure.
Long-Term Cost Savings
High resistance to thermal fatigue and distortion reduces component replacements and maintenance costs in extreme heat environments.
Key Applications of Hastelloy X Washers
| Industry Sector | Application | Operating Environment |
|---|---|---|
| Gas Turbine Engines | Combustor cans, transition ducts, flame holders, and tailpipes | High-velocity burning gases at extreme operating temperatures |
| Industrial Furnaces | Retorts, baffle plates, furnace muffles, and structural support bolting | Carburizing, nitriding, and highly oxidizing heat-treat environments |
| Petrochemical Processing | Pyrolysis tubing flanges, steam reformer outlets, and catalyst grids | Thermal cracking operations exposed to high carbon and sulfur loads |
| Aerospace Exhaust Systems | Afterburner components, tail cones, and thermal shield fasteners | Dynamic thermal shock and severe vibrational loads |
| Nuclear Engineering | High-temperature gas-cooled reactor (HTGR) core structural joints | Helium cooling loops exposed to elevated operating temperatures |

Frequently Asked Questions
Hastelloy X offers an exceptional balance of high-temperature creep strength, oxidation resistance, and fabricability at continuous service temperatures up to 1200°C (2200°F).
Yes. Alloy X is highly resistant to carburization and nitriding, making it suitable for industrial furnace components and heat-treating hardware.
While optimized for extreme high-temperature service, Hastelloy X retains good ductility and impact strength at sub-zero temperatures.
Our Hastelloy X washers are supplied in the solution heat-treated condition (1177°C followed by rapid quenching) for optimal high-temperature performance.
All shipments include complete EN 10204 3.1 Mill Test Reports covering heat chemistry, tensile properties, hardness values, and PMI verification.
