Hardening
The term hardening is often used in the commercial heat-treating industry to describe the process otherwise known as quench and tempering. Steel is heated to an austenitizing temperature, then quenched in oil or water whereupon it is subsequently tempered to increase toughness. The goal of hardening/quench and tempering is to produce a high hardness and strength in a steel part, so that the material has the required engineering properties called for by the design. Cincinnati Steel Treating performs hardening operations on many different types of steel, and we use many different types of processes for hardening.

Hardening/Quench and Tempering Applications
Steel is considered hardened when it undergoes the austenite-to-martensite solid state phase transformation. This is accomplished by heating the steel part above the austenite transformation temperature and then quenching it in a fast cooling medium such as water, oil, or air. The strengthening
