How to benefit from Expanite® surface hardening & heat treatment solutions in the

defense & aerospace Industry

Aerospace & Defense surface hardening

Surface Hardening & heat treatment in the Defense & Aerospace Industry

The Expanite® surface hardening technology continue to support the commercial aircraft, defense  and aerospace industries in meeting increasing market pressures and rising demands for performance, reliability, and supply chain resilience.

In aerospace and defense manufacturing process safety has a top priority. This sets high requirements on mechanical properties, corrosion resistance  and dimensional stability of critical components Whether the challenge is wear, galling or corrosion resistance, Expanite guarantee  the most ideal surface hardening solutions tailored to specific needs and demands of each application of your components. 

Key factors the Defense & Aerospace Industry

In the Defense industry, fast development speed and stable supply chain are key priority. For commercial aircrafts performance and utilization including fuel efficiency are critical parameters. Expanite is playing an increasing role in all three industries combining deep expertise knowledge about critical materials, with a dedicated technical team working closely with customers to optimize material selection, machining, and application design.

This knowledge sharing has resulted in several stainless steel and titanium projects where components have been made lighter, stronger, and more durable.


Where component reliability and service life are critical, Expanite heat treatment enhances the performance of stainless steel and other high-value materials by reducing wear, corrosion, galling and the risk of early failure.

Challenges in the Defense & Aerospace Industry

Critical components must perform reliably under demanding conditions, with no compromise on material integrity or lifetime. Expanite improves surface performance where reliability, precision and durability are essential.
