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.A solid solution strengthening grade, Alloy X has good strength and corrosion resistance in reducing carburising atmospheres.
The butt welding cap is a component of the container and is connected to the cylinder by welding. (As shown below) According to different geometric shapes, it can be divided into spherical, elliptical, dish-shaped, spherical crown, cone shell and flat cover. Among them, spherical, elliptical, dish-shaped and spherical crown heads are collectively referred to as convex heads. In terms of welding, it is divided into butt welding heads and socket welding heads. It is used for various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. The materials include carbon steel (A3, 20#, Q235, Q345B, 16Mn, etc.), stainless steel (304, 321, 304L, 316, 316L, etc.), alloy steel (15Mo3 15CrMoV 35CrMoV45CrMo), aluminum, titanium, copper, nickel and nickel alloys, etc.
