It is a nickel-chromium-iron-molybdenum superalloy renowned for its exceptional combination of high-temperature strength, oxidation resistance, and fabricability. Developed to perform in the most demanding industrial environments, Hastelloy® X (also known as Alloy X) offers outstanding performance up to 1200°C (2200°F). Its resistance to carburization and nitriding makes it an essential material for aerospace and industrial gas turbine components, as well as for structural applications in industrial heating furnaces. As a leading Hastelloy X supplier in the UAE, Nifty Alloys provides this high-performance material directly from our Sharjah stock to meet the critical demands of your projects.
Alternate names for this alloy include Hastelloy Alloy X, Hast X Alloy, and its universal designation, UNS N06002.
The reason Hast X alloy excels in high-temperature, oxidation-resistant service is its carefully balanced chemical composition. The high nickel content provides a stable austenitic structure, while significant chromium levels enable the formation of a protective, adherent oxide scale that resists spalling at extreme temperatures. Molybdenum contributes substantially to its solid-solution strength at temperatures where many other alloys would fail. This unique synergy of elements ensures reliable mechanical integrity and environmental resistance in combustion zones, exhaust systems, and heat-treating equipment.
