What is Inconel 722 nickel alloy?
Inconel 722 is a high-performance nickel alloy developed by Special Metals. It is a nickel-chromium-iron alloy that contains high chromium and molybdenum, as well as a certain amount of cobalt and tungsten.
What are the features of the Inconel 722?
This alloy has excellent corrosion resistance and high-temperature strength, so it is widely used in aerospace, petrochemical, energy and other fields.Below, the classification composition and properties of superalloys are introduced

The corrosion resistance of other ( ) Inconel 722 is mainly due to its high chromium content. Chromium is an important corrosion-resistant element that is able to:
A dense oxide protective layer is formed to prevent further corrosion of the metal. In addition, the addition of molybdenum also enhances the combination.
The corrosion resistance of gold and the high temperature strength of the alloy is improved.
In high-temperature environments, the Inconel 722 is still able to maintain excellent performance. Its high-temperature strength is mainly due to nickel.
and chromium's solution strengthening effect. In addition, the addition of cobalt and tungsten also enhances the high-temperature strength and creep properties of the alloy.
In addition to corrosion resistance and high-temperature strength, Inconel 722 has excellent processability and weldability. It can.
It is processed by various conventional processing methods, such as cutting, bending, drilling, etc. In addition, it can also pass.
Conventional welding methods are used for welding, and the performance after welding is similar to that of the base metal.
