Hastelloy X

Hastelloy X is a nickel-chromium-molybdenum alloy with added cobalt and tungsten. Hastelloy X has excellent oxidation resistance at high temperatures up to 1200°C and can also be used in neutral and reducing atmospheres. At the same time, it can resist carbonization and nitriding atmosphere. The alloy has moderate durability and creep strength at high temperatures of 900°C. It has good oxidation resistance and corrosion resistance, good hot and cold processing formability and welding performance, and is suitable for making components such as aeroengine combustion chambers for long-term use below 900°C, as well as high temperatures with working temperatures up to 1080°C for short-term use. Hastelloy X has excellent oxidation resistance up to 1200°C, good high temperature strength, good formability and weldability, and good resistance to stress corrosion cracking. It is widely used in civil industry and aviation engines for the manufacture of steam turbines (combustors, rectifiers, structural covers), industrial furnace components, support rollers, grids, ribbons and radiant tubes, and spiral tubes in petrochemical furnaces.

Alloy X is known for its excellent high temperature strength withstanding up to 2200° F. The alloy can also be easily fabricated with forming and welding characteristics by both manual and automatic methods. Additionally, Alloy X is corrosion resistant, heat resistant and oxidation resistant, being able to withstand reducing or neutral atmospheres and oxidation.
