Product Description

Inconel 718 plate is made of a special type of high-strength superalloy whose nickel-chromium base makes it resistant to corrosion, high pressures and extreme temperatures up to 700°C. Due to its unique properties, Inconel 718 plate has become useful in a wide range of applications from manufacturing operations to military equipment and the aerospace industry. Inconel 718 is a high-strength, high-temperature, corrosion-resistant nickel-based alloy whose chemical composition includes elements such as 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. It also works well at low temperatures. This nickel superalloy has the inherent ability to 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 plate can be manufactured through a variety of processing methods, such as forging, hot rolling, cold drawing and welding. However, at high temperatures, it is prone to oxidation and hardening, and appropriate preheating and post-processing measures need to be taken to reduce this phenomenon.
