Expanite: An alternative to fluoroplastic coatings

Expanite, the technology for surface hardening of stainless steel and titanium is used more and more frequently when it comes to alternatives to classic fluoroplastic coatings such as Teflon®, Halar® or Xylan®. In addition to technical and commercial advantages, the environmental compatibility and sustainability of the Expanite process are playing an increasingly important role for customers.

The Expanite technology is based on a gas process in which carbon and nitrogen are diffused in the component surface. The otherwise comparable soft and wear-prone stainless steel material hardens by a factor of up to 10 and while classic diffusion processes impacting corrosion resistance of the material, the Expanite processes generally improve the corrosion properties of the component.

Expanite’s gas-based diffusion process is significantly more energy-efficient and environmentally friendly than comparable wear protection processes.

The Expanite technology offers a solution for austenitic, martensitic, ferritic, and duplex stainless steels as well as for expensive nickel-based alloys such as Inconel and Hastelloy. Moreover, ExpaniteHard-Ti, which the Expanite team of experts has developed to market maturity in recent years, is used for titanium grades.
