Expanite A/S

With Expanite surface treatment it’s possible to increase the surface hardness of stainless steels by up to 10 times, while maintaining or even enhancing corrosion resistance. This method is considered unique since it’s suitable for austenitic-, ferritic-, martensitic and duplex stainless steels. Parts can be treated with extremely short lead times—a few days—which is previously unseen within surface hardening of stainless steel. The Expanite technology can significantly increase the value of products across many industries—from knives, valves, mixers, and grinders for the food industry, to pumps and extruder screws, or injection parts for the automotive sector, as well as screws, bolts, and washers. At its core, Expanite offers 3 different processes, each of which can be optimized according to customers’ requirements in terms of abrasion, galling, corrosion and scratch resistance. This means that Expanite can develop and customize solutions for a wide variety of companies and industries. With the opportunity of processing most common stainless steel alloys - either in-house or at Expanite's treatment centre - the company offers significantly improved corrosion, wear, fatigue and scratch resistance.
