Hardning performance Expanite improving wear, galling and corrosion resistance
Hardening results with Expanite processes
At Expanite, we believe in proof through performance.
Our surface hardening and heat treatment test results demonstrate that Expanite hardening processes improve wear, galling and corrosion resistance, extending lifetime for stainless steel and titanium parts.
Our results are based on international standards, including ASTM G133 wear tests and ASTM G98 galling tests, performed on stainless steel and titanium parts.
The results confirms that the Expanite surface hardening process significantly improves wear, galling, and corrosion resistance.

Improving Performance
By improving wear, galling and corrosion resistance, the Expanite surface hardening technology reduce unplanned downtime, replacement frequency, and maintenance costs.



What is Wear resistance?
Even stainless steel and other high-value alloys can suffer from abrasive wear, sliding wear and repeated mechanical contact. Expanite surface hardening is designed to increase surface hardness and wear resistance, helping components last longer in demanding operating environments.

What is Galling Resistance
Galling is a common failure mechanism in stainless steel assemblies where surfaces seize, stick or cold-weld under load. Expanite surface hardening improves galling resistance and is relevant for components such as valves, fasteners, pump parts, shafts, bearings, fittings and moving assemblies.
