Hastelloy X nickel alloy is a nickel-chromium-molybdenum alloy with added cobalt and tungsten. Hastelloy X alloy exhibits excellent oxidation resistance at temperatures up to 1200°C and can also be used in neutral and reducing atmospheres. In addition, Hastelloy X alloy is resistant to carbonization and nitriding.
The characteristics of Hastelloy X nickel alloy are as follows:
1) Excellent oxidation resistance at temperatures up to 1200°C;
2) Good strength at high temperatures;
3) Has good formability and weldability;
4) Good resistance to stress corrosion cracking.
Hastelloy However, pulsed arc welding is the preferred welding method. Before welding, the material needs to be solution treated to remove the oxide layer, oil stains and various traces. An area approximately 25 mm wide on both sides of the weld needs to be polished to a bright metal surface. Welding uses low heat input and interlayer temperature does not exceed 100°C. Hastelloy X does not require pre-weld and post-weld heat treatments.
