Inconel 718 Bar Description
Inconel 718 is a high-strength, high-temperature, corrosion-resistant nickel-based alloy whose chemical composition covers nickel, chromium, molybdenum, iron, cobalt, aluminum, titanium, zirconium, carbon, and manganese. Inconel 718 has a melting point of 1430°C and displays effective heat and temperature resistance. This nickel superalloy can create a strong and stable oxide layer when heated. In addition, the layer makes this Inconel variant significantly resistant to oxidation, thus protecting it from corrosion. Inconel 718 bar can be manufactured through a variety of processing methods, such as forging, hot rolling, cold drawing and welding. It is prone to oxidation and hardening at high temperatures, and appropriate preheating and post-processing measures are needed to prevent the phenomenon.
