The BHT shop is a full service heat treating facility. Our furnaces are microprocessor controlled to assure accuracy and repeatability. Our equipment includes:

• Double end car furnace. Work area is 22 feet long by 8 feet wide by 5 feet high. Each car can accept a loading of 50,000 pounds. Temperature range is 500F to 1,850F. Crane capacity over the furnace is 5 tons.
  
• Recirculating type furnaces. Work area 49 1/2" diameter by 12 feet high vertical furnaces. The temperature range is 300F to 1,650F. Uniformity is plus or minus 10F and equipped with Inconel retorts 48” diameter by 7 feet high. These units are for annealing, normalizing, stress relieving, solution treating and aging, tempering and nitriding.
• Atmosphere controlled radiant tube furnaces. Work area is 30"x36"x48". Temperature range is 1,200F to 1,850F. Uniformity is plus or minus 15F. This equipment is designed for carburizing, carbonitriding, and air hardening of high carbon and high chrome steel. Other functions include hardening of alloy steels, annealing, normalizing and silver solder brazing. Each unit has a 2,000 gallon oil quench tank. The furnace is fully automatic, including dew point control. Hearth loading is 2,500 pounds.
  
• Bright hardening equipment. Work area 10" x 6" x 30". Temperature range is 1,200F to 2,150F. Uniformity is plus or minus 10F. Horizontal straight through alloy muffle. Designed for copper brazing, bright hardening and annealing of stainless steels as well as hardening of air hardened tool steels. Atmospheres include hydrogen or dissociated ammonia.
• Air recirculating furnaces with alloy fans. Work area is 30" x 30" x 30". Temperature range is 100F to 850F. Uniformity is plus or minus 5F. Used for tempering and aging of aluminum.
• Induction hardening unit. The unit is 200KVA rated and is used for selective hardening of gear teeth, cams and shafts.
• Vacuum furnace. For the heat treatment of air hardening tool steels and stainless steels. Work area is 20" x 34" x 12”. The maximum temperature is 1,950F.
• Lucifer furnace. The unit size is 13" x 6" x6". Atmosphere is Daimon Block or any other protective atmosphere.
• Fluidized bed furnace. 8 1/2" x 18" deep.
• Flame hardening equipment. For large gears, cams and shafts.
• Atmosphere generators. Two endothermic units, each rated for 750CFH and two ammonia dissociators rated at 1,000 CFH each.
• Deep-freeze equipment. For freeze temperatures to -125F.
• Sand blast and glass beading equipment. Vacuhone for cleaning of parts after heat treatment.
• Safety equipment. Safety equipment includes over-temperature control instruments, vaporstats in combustion air lines, pressure controls in the gas lines and safety shut-offs in case of air, gas or power failure. All process control instruments are of the recording type.
  

Our quality control is maintained by the use of certified hardness testers as well as certified instruments and furnaces. All work carries a job ticket through processing. All pertinent information about the part, process, acceptance criteria, etc. is recorded each step of the way. Company inspectors check all process variables and records are kept indefinitely.

All thermocouples are certified and traceable to the National Bureau of Standards. Purity of gases is certified. Physical and chemical testing is certified as well.
