The Expanite surface hardening technology can be used on complex shapes and geometries uniformly and can achieve full coverage of difficult to reach areas which is not possible by other treatment methods.

One of the key advantages of Expanite’s surface hardening and heat treatment technology is that the process is deformity free.

Unlike traditional hardening methods that expose parts to extreme temperature gradients or rapid quenching, the Expanite process operates in a fully controlled thermal environment.

This ensures that components maintain their original dimensions and tolerances — even when exposed to high temperatures during treatment.

For precision parts, such as those used in valves, pumps, medical device instruments, or aerospace applications, even a small amount of distortion can lead to assembly challenges or performance issues.

Expanite eliminates that risk, ensuring dimensional stability and perfect fit every time.
