Seco Warwick, Meadville, Pa., has been awarded a new technology patent for Pit-LPC furnaces that have set a new direction for carburizing processes. The LPC abbreviation refers to the “low pressure carburizing” formula, which is a process conducted under pressure or in a vacuum, in an oxygen free atmosphere by means of hydrocarbons.

The forge quenching process requires that quenching equipment be placed as closely as possible to the equipment used in the forging stage. Since the early 1960s, various direct-forge and quench equipment has been installed in this manner, thus enabling the use of carbon steels, which have good hardenability from grain growth and high dislocation density from the thermomechanical deformation performed during hot forging.
