Endothermic

When steel is heated above approximately 1400F, it reacts with any oxygen in the atmosphere and its carbon is pulled right from its surface. This creates a very undesirable condition known as decarburization or scale. To combat this, we generate our own endothermic gas that gets pumped into the atmosphere of the furnace and displaces all of the oxygen present. In addition to this carrier gas, a carbon-sensing probe directs precise amounts of natural gas into the atmosphere to control the carbon level required for the process and materials being hardened.

As a result, we can neutral harden, carburize or normalize any carbon or alloy steel to your specifications and maintain a nice scale-free surface. The internal oil quench tank of each of our three endothermic furnaces allows us to quench directly into oil without the parts ever seeing the light of day.

We currently have three endothermic, integral oil quench furnaces for processing your steel.

E1

24” wide x 36” long x 14” high.
800-lb capacity.

E3

36” wide x 60” long x 40” high.
4100-lb capacity.

E4

36” wide x 54” long x 45” high.
4100-lb capacity.

Nine accompanying tempering/stress relieving furnaces allow us to temper your steel to the appropriate hardness levels that you require.
