This solid solution strengthened grade has good strength and excellent oxidation resistance to 2000°F. Alloy X has excellent resistance to reducing and carburizing atmospheres, making it suitable for furnace components. Due to its high molybdenum content, Alloy X may be subject to catastrophic oxidation at 2200°F. Alloy X is welded by all common methods such as gas tungsten arc, gas metal arc, shielded metal arc, electron beam and resistance welding. Use matching filler metal, keep interpass temperature low. After severe forming, fabrications may be annealed 2150°F, 15 minutes per 1/8" of thickness, rapid air cool.
