What is Parker Suparcase Ferrule Hardening Process?

Not all hardening processes are equal. Parker's Suparcase™ proprietary ferrule hardening process gives the differential hardness for superior grip and performance in various applications. Watch to discover Parker's invisible advantage.

The Parker Suparcase™ surface treatment is a unique process that allows stainless steels and other alloys to be hardened without affecting and even increasing the corrosion resistance of the given materials. Parker has been using the proprietary Suparcase™ process to surface harden stainless steel ferrules for approximately 30 years. The process achieves a carbon supersaturated surface layer by altering the passive oxide layer on the stainless steel surface without any detrimental effects.
