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 1204°C.The alloy has good high temperature strength coupled with oxidation resistance up to 1093°C.This Alloy is readily weldable using matching filler wires. After severe forming, fabrications may be annealed at 1177°C, 15 minutes per 1/8″ of thickness, rapid air cool.Weld Neck Flanges is a kind of flange with a cone neck and butt welded with the cylinder or pipeline. Due to the transition structure of the cone neck and butt welded connection, the strength and stiffness of the flange are strengthened, and the sealing is better than that of the flat welded flange. It is suitable for occasions where the pressure and temperature are high or the sealing requirements are high.
