Product Overview –Hastelloy X Pipes
Hastelloy X Pipes, are premium nickel-chromium-iron-molybdenum alloy pipes specifically developed for outstanding performance in extreme high-temperature and oxidizing environments. Unlike Hastelloy B and C series alloys, which primarily focus on corrosion resistance, Hastelloy X is engineered to combine exceptional oxidation resistance, high-temperature strength, excellent fabricability, and outstanding creep resistance, making it one of the most trusted materials for aerospace and industrial heat applications.
Hastelloy X maintains excellent mechanical properties at temperatures exceeding 1200°C, while resisting oxidation, carburization, nitriding, and thermal fatigue. These characteristics make the alloy highly suitable for gas turbines, combustion chambers, industrial furnaces, petrochemical plants, nuclear reactors, aircraft engines, and heat treatment equipment operating under continuous thermal cycling
