Surface Hardening of Stainless Steel and Titanium Alloys

The surface hardening engineering firm Expanite has developed an advanced gaseous process for low temperature surface hardening of stainless steel. The gaseous process allows precise control for accurate tailoring of to the materials’ properties and can be applied to austenitic, martensitic, duplex and PH steels imparting the treated material with superior wear, scratch and corrosion resistance including the prevention of galling. Furthermore the fatigue and cavitation resistance of stainless steel components can be dramatically improved. Recent developments indicates that surface hardening of titanium and its alloys is indeed possible.

The Expanite technology is installed in state-of-the-art Seco/Warwick furnace equipment and adapted and refined for the optimal user experience. The solution is designed to operate directly in the customer production line or can be provided on a day-to day basis from the heat treatment center in Denmark.
