Key Features:

Corrosion Resistance:

Inconel X-750 can resist corrosion from reducing or oxidizing conditions which brings in a wide-scale application for this alloy.

Creep Resistance:

This property in alloy X-750 comes from the even distribution of intragranular gamma prime.

Rupture Resistance:

While the creep resistance in Alloy X-750 comes from the gamma prime, its rupture strength comes from the closely-knit microstructure of the grain-boundary area.

Possible Alternative Grades:

Inconel 617:

This solid alloy alternative of X-750 flaunts properties such as high-temperature strength, oxidation resistance, corrosion resistance, high weldability, and more.

Inconel 625:

Popular due to its acid-resistant abilities, Inconel 625 brings in excellent weldability to the market.

Inconel 718:

The excellent weldability in Inconel 718 comes from its Gamma double strengthened composition.

Frequently Asked Questions:

How to increase Inconel X-750’s load-carrying capacity?

When fabricating springs from Inconel X-750 to be used in the services with low temperatures, they might undergo cold-pressing post precipitation treatment in order to increase its load-carrying capacity moderately.
