Hastelloy In this article, we will comprehensively analyze the characteristics, welding methods, chemical composition, mechanical properties and application fields of Hastelloy X.
**Features of Hastelloy X**
Hastelloy X has the following features:
1) Excellent oxidation performance 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.
**Welding of Hastelloy X**
Hastelloy However, pulsed arc welding is preferred. Before welding, the material needs to be solution treated to remove scale, oil and various traces. An area approximately 25mm wide on both sides of the weld needs to be polished to a bright metal surface. Use low heat input when welding and the interpass temperature does not exceed 100°C. Hastelloy X does not require pre- and post-weld heat treatments.
