ELLWOOD National Forge heat-treating facilities are capable of thermal stress relieving, annealing, normalizing, quenching, and tempering. At ELLWOOD National Forge we can offer both vertical and horizontal heat treatment. With 14 vertical heat treat furnaces we are capable of heat treating parts up to 30’ in length and 76” diameter. Our six horizontal furnaces can handle parts 288’ in length and 168” wide.   Our furnaces are in close proximity to our water and oil quench tanks allowing for an efficient transfer system, exceptional heat-treating control, and consistency. ELLWOOD National Forge also has specialty on-site horizontal and vertical spray quench capabilities. 

All furnaces are equipped with state-of-the-art controls to assure accurate temperature and furnace operation during the thermal cycle process. Heat stability testing capabilities are available to measure the stability of high speed rotating parts under operating conditions. In addition to heat treating low alloy steel forgings, ELLWOOD National Forge has the capability to heat treat stainless, titanium and a wide range of oilfield and dense specific alloys, meeting our customer’s critical application requirements.
