Why Does the IntensiQuench® Process Work?

Due to very fast and very uniform cooling in the first step of the Intensi-Quench® process, the entire part surface reaches the martensite transformation region at the same time regardless of the part geometry and thickness variation. Therefore, the hardened martensitic structure starts forming in a matter of seconds simultaneously throughout the whole part surface area creating a firm case or shell with high compressive stresses on the part surface.

This compressive case acts as a "die" holding the part and minimizing distortion. After tempering, part toughness and fatigue life are improved over conventional quenching methods. The result is a SupR-STRONG^TM part with little part distortion.
