Hastelloy X-Pulver Description
Hastelloy X (Alloy X, UNS N06002) is a nickel–chromium–iron–molybdenum alloy that demonstrates oxidation resistance, processability and high-temperature strength. It has been verified to resist stress corrosion cracking in petrochemical applications. The X alloy retained ductility after exposure for 16 000 hours at temperatures of 650, 760 and 870°C (1200, 1400 and 1600°F).
Hastelloy X-Pulver permits forming and welding operations. It can be forged and cold formed owing to adequate ductility. The X alloy is weldable by manual and automated methods; welding techniques include shielded metal arc welding (SMAW), tungsten inert gas welding (TIG) and metal inert gas welding (MIG). Resistance welding is also possible.

Hastelloy X-Pulver Applications
Hastelloy X-Pulver is used in gas turbine engines for components in the combustion zone. These components include transition ducts, combustion chamber cans, spray bars and flame holders. It is also applied in afterburners, exhaust pipes and cabin heaters. Given that the alloy resists oxidising, reducing and neutral atmospheres, it is employed in industrial furnaces. Furnace rollers manufactured from this alloy remained operational after 8 700 operating hours at 1177°C (2150°F). HASTELLOY X is used in the chemical process industry for retorts, muffle furnace parts, catalyst support grids, furnace deflections, pyrolysis tubes and components in rapid dryers.
