Hastelloy X is a kind of nickel base superalloy with high iron content, which is mainly strengthened by solid solution of chromium and molybdenum. It has good anti-metallization and corrosion performance, medium endurance and creep strength below 900℃, good cold and hot processing formability and welding performance.
Used in the manufacture of aero-engine combustion chamber parts and other high temperature parts, under 900℃ for a long time, short time working temperature up to 1080℃.

1. Excellent oxidation resistance at high temperature(>1200℃)).
2. Good high-temperature strength.
3. Good formability and weldability.
4. Good resistance to stress corrosion cracking.
Because of its corrosion resistance in various atmospheres at high temperature and excellent high temperature strength, HastelLoyx has been widely used in various high temperature environments.
Typical application fields:
• Industrial and aviation steam turbines (combustion chambers, rectifiers, structural caps)
• Industrial furnace components, support rollers, grates, ribbons and radiator tubes
• Spiral tubes in petrochemical furnaces
• High temperature gas cools the nuclear reactor
