OUR PROPRIETARY PROCESS
The boron hardening process is not a coating, heat treatment or another form of mechanical, chemical or alloying bonding to the surface (like plasma impingement). Our process diffuses into the host material to form an intermetallic structural that greatly improves the resistance to wear, cavitation, corrosion, abrasion, erosion & impact.
Our high-quality, long-lasting valves and innovation have fostered, long-term relationships with our customers, suppliers, and employees.
