Hastelloy X is a high-temperature, corrosion-resistant nickel-chromium-iron-molybdenum alloy. It has excellent high-temperature strength and good oxidation resistance up to 1200°C, making it suitable for use in a range of applications that require resistance to high temperatures and harsh environments.
Hastelloy X is often used in gas turbine engine components such as combustor cans, flame holders, and transition ducts. It is also used in industrial furnace components such as muffles and radiant tubes, as well as in chemical processing equipment and heat exchangers.
This alloy has a unique combination of mechanical properties that make it suitable for use in high-stress applications at elevated temperatures. It has good ductility, high strength, and excellent resistance to thermal fatigue and thermal shock. Additionally, it has good resistance to both oxidizing and reducing environments, including wet chlorine and sulfuric acid.
Hastelloy X is typically supplied in the solution-annealed condition, which provides good ductility and toughness. It can be easily welded using common welding techniques, and can also be formed and machined using standard methods.
Overall, Hastelloy X is a versatile and reliable alloy that offers excellent performance in high-temperature, corrosive environments. Its unique combination of properties makes it an ideal choice for a range of demanding applications in the aerospace, chemical processing, and industrial sectors.
