Expanite® processes leave no soot or other residues on the hardened surface, eliminating the need for any post treatment.

Traditional hardening and coating methods often require post cleaning steps to remove soot, residues, or chemical by-products.
These additional processes not only increase cost and handling time but can also risk surface contamination or distortion.

With Expanite, none of that is necessary. Our patented surface hardening processes ensure that parts are ready for immediate use or assembly after treatment — with no blasting, polishing, or chemical cleaning required.
This significantly simplifies logistics, reduces turnaround time, and ensures consistent, high-quality results.

At Expanite, the absence of post cleaning is not a coincidence — it’s a direct result of how our surface hardening and heat treatment processes are designed.
The Expanite technology is a fully controlled, dry, and gas-based treatment that leaves the surface of stainless steel and titanium parts completely clean and metallically pure.
Because there are no coatings, oils, or carbon deposits involved, components come out of the furnace exactly as they went in — only stronger, harder, and more resistant to wear, galling, and corrosion.

Because Expanite’s heat treatment technology produces no waste, it’s also better for the environment.
There are no acids, solvents, or cleaning agents involved, which means no wastewater or hazardous materials to dispose of.
This makes the process both operator- and environment-friendly, aligning perfectly with our ISO14001-certified commitment to sustainability.
For our customers, this translates into a cleaner production chain, lower maintenance costs, and an overall reduction in carbon footprint.
