Atmosphere Heat Treating

Some heat treating applications require that metal surfaces are hard while the interior portion of the metal remain relatively soft. A hard surface and soft metal inner core can better withstand abrasive contact, high stress, and fatigue. This process is also known as case hardening.  Katy Heat Treat incorporates the use of atmosphere ovens for applications and specifications that require case hardening heat treat methods. 


Process

Carburizing is a popular method of case hardening specified by many of today’s engineers.  The carburizing process takes place in an atmosphere furnace where parts are heated in a controlled temperature and atmosphere.  Carbon gas is induced to low-carbon steels surfaces which are then quenched by plunging into a liquid. The carburizing causes the high-carbon metal surface or “case” to become very hard, while the low-carbon metal core remains relatively soft.

Katy Heat Treat can assist customers with almost any atmosphere heating requirement. We also use hot oil quenching methods to reduce distortion, and to further reduce distortion, Katy Heat Treat has the capability to rack almost any part.


Katy Heat Treat uses a high-performance gas system to control case depth requirements called out by our customer’s unique specifications. We employ above-standard quench rates and temperature uniformity resulting in repeatable case depths and uniform hardness.
