GAUGE MATERIAL OPTIONS

The best gauges start with the most appropriate material in each use case.  Let us know what you need or allow our engineers to recommend the best options.

WPS – Oil hardening tool steel hardened to Rc 60-62.

WPX – A powdered metal high speed steel hardened to Rc 62-64; noted for its higher wear resistance without sacrificing toughness. Recommended for high frequency gauges.

WPZ – A powdered metal high speed steel hardened to Rc 64-66; extremely high wear resistance and moderate toughness. Recommended for master gears.
