The valve stem is an important part of the valve. It is used for transmission, connecting actuators or handles. It needs to have good impact toughness, wear resistance and corrosion resistance. Therefore, many valve stems are usually made of Inconel 718 material.……

Due to the high melting point of nickel-based alloys, the requirements for its own purity are also very high. The nickel-based alloy smelting process is different from the conventional smelting method. There are three main processes: VIM, ESR, VAR……

The internal stress of nickel alloys is due to the internal forces that interact between the various parts of the metal when the nickel alloy materials (such as plates, forgings, wires, bars, etc.) are deformed by external forces, humidity changes to resist this.……

High-temperature alloys can be classified according to trademarks, basic elements, strengthening methods, and forming processes. Click to view details.……

Hastelloy C-276 welded pipe is not subjected to cold rolling and solution annealing treatment after welding. The dendrite structure produced by the weld will greatly reduce the corrosion resistance of C-276 welded pipe, resulting in easy corrosion at the weld of the welded pipe.……

Inconel 718 and Inconel X-750 are both corrosion-resistant and high-strength nickel-chromium-iron alloys, which are widely used in the aerospace industry. What are the differences in performance and processing methods?……

Inconel 718 is a precipitation hardening high-performance nickel base superalloy, which can work for a long time at a high temperature above 600 ℃, and has good workability and structural stability. It has become an ideal material for special industries such as petrochemical indu...……

Inconel 690 is a single-phase austenitic nickel-based corrosion-resistant alloy with excellent comprehensive performance. It has high strength, metallurgical stability and workability. Alloy 690 welding wire has high welding quality and the most ideal welding seam purity. It is w...……

Inconel 690 alloy is prone to hot cracks and pores during welding. Because Alloy 690 solidifies, the liquid film formed by low melting point eutectic or low melting point compound remains in the grain boundary zone, so it is prone to cracking under the action of shrinking force. ...……

Casting is the process of filling the liquid metal into the mold cavity under the action of external force or gravity. When the liquid metal cools, it can obtain the required shape blank. Nickel base alloy can dissolve a large number of alloy elements to form a coherent and order...……
