The CBH 124 box furnace is specifically designed for neutral hardening. With the Nitrogen/Propane Atmosphere Package the furnace will do neutral hardening with virtually no decarburization or oxidation. Gas levels and resulting carbon levels obtained with the propane are set empirically with the manual controls. The CBH 124 incorporates many features like a compact control panel/stand, pneumatic vertical door, silicon carbide hearth, heat shield, peephole, heavy gauge low voltage elements,program control, high limit control, low mass ceramic fiber insulation, etc. that are normally options on many of L&L’s other furnaces. This makes for a very complete and “choice free” versatile furnace. The maximum temperature of 2250ºF (1230ºC) allows this furnace to be used for high speed tool steels. The CBH 124 is highly uniform in temperature gradient.
