Vacuum Oil Quenching
(Click on thumbnail to enlarge)
Our vacuum department includes seven furnaces with a range of capability second to none in the Northeast. We have an ultimate vacuum capability of 10-5 torr. Our vacuum quench furnaces can quench work from temperatures as high as 2150°F (1175°C). We use nitrogen or argon for quenching at pressures up to 60 psig (5 bar). Our continuous pressure quench furnace is unique in that it is capable of producing cool rates approaching that of oil yet with minimal distortion associated with gas quenching. HHT routinely hardens 4340, 4130 materials in section sizes up to 1/4" nominal.
Hayes VMH-PQ-242436 Single Chamber Gas Pressure Quench Furnace. This furnace is used for larger vacuum work requiring rapid gas cooling andlor high vacuum at temperatures up to 2150°F (1175°C)
Whether 400 series or carbon steels; Spectrum Thermal Processing can help you harden and temper your bearing components.
Spectrum Thermal Processing utilizes pressure quenching furnaces using 2 and 6 bar pressure, gases are nitrogen 2 and 6 bar and argon at 2 bar.
Vacuum integral oil quenching is a specialty at Hayes Heat Treating. In addition to the hardening HHT provides deep freezing as well as air, atmosphere and vacuum tempering of your products.
