Bench Top Tempering Heat Treat Furnace and Tempering Oven rated to 1250°F
Tempering / drawing is a post-quenching or post hardening heat treatment process to "draw the temper" (reduce brittleness, increase toughness) after hardening. Recommended soaking time is 2 hours for each inch of cross section. Keith Bench Top Tempering / Drawing ovens and furnaces rated to 1250°F include a convection fan and a vertical rising door for operator safety and are often a companion to the Bench Top Metal Hardening Furnace rated for 2250°F (check out our space saving dual chamber furnaces). Options include inert gas atmosphere to reduce scaling, AMS 2750E instrumention type D or CQI-9 package for NADCAP certification and various temperature controllers.

Similar to the Bench Top Hardening Heat Treat Furnaces rated for 2250°F, the Keith Bench top annealing furnaces comes in a variety of model sizes and configurations with a various options available including a 2000°F temperature upgrade package, viewing port, digital recorder for data capture, furnace bench stands and special controls. For space saving, we also build dual chamber heat treat furnaces with the upper chamber for hardening and a lower chamber for tempering / drawing. It has become the industry standard in the job shop or R&D laboratory where uniform temperatures between 300°F – 1250°F of ±10°F are required.
Every Keith Bench Top Drawing furnace is produced with a microprocessor-based controller, easy to change alloy wire heating elements, porcelain hearth plate, heavy gauge sheet steel furnace case, quality insulating fire brick backed up by 1800°F fiber board insulation, door safety switches, and a counter balanced vertical rising door designed to keep the hot face away from the operator.
Our benchtop furnaces are built with easy to change standard resistance wire heating elements plates.
