Patented technology
Expanite® is a game-changing surface hardening process for stainless steel coating that will make you and your customers much more competitive.
Our patented and proven technology, scientific know-how and flexible delivery model significantly improves product performance, quality, and reduces costs.

Expanite - not another coating
The Expanite® heat treatment effectively removes the oxide film covering stainless steels. This allows controlled incorporation of carbon and nitrogen atoms in the underlying metal. The hardened layer is characterized by an expansion of the material structure. We call this zone expanded austenite, expanded martensite, or simply: Expanite.
