		Tool & Die Vacuum hardening serves many advantages to the Tool & Die market with low part distortion and superior part finish due to the oxygen free atmosphere. Each vacuum is equipped with controllers capable of running precise recipes that control all aspects of the hardening and quenching cycle. Our furnace operating temperatures range from 1400° F - 2400° F with up to a 6-bar nitrogen quench. Our recipes or cycles can be customized to develop the microstructure and mechanical properties that you need to achieve for your desired application.

		Quench & Temper In order to achieve the correct measures of hardness, strength, and ductility, metals are often required to be hardened and tempered. Our batch hardening furnaces operate in a range of 1400°F - 1800°F with an oil quench in either a still or agitated state at 150°F - 225°F. Our tempering furnaces range from 300°F - 1200°F depending on the desired mechanical properties. We have the capability to incorporate special fixtures and racking to allow parts to be separated or oriented in a desired manor.




		Case Hardening / Carbonitriding Case hardening is a process used to develop a hard surface layer on a material while leaving the more ductile center intact. This treatment develops a hardened surface by introducing both carbon and nitrogen to the surface of the material. We can process case depths from 0.003" to 0.020".




		Atmosphere Annealing / Stress Relieving Often times a material needs to be softened in order to make it easier to machine. Annealing is a heat treatment that is designed to soften the material and also produce a desired microstructure for such processes as cold forming and stamping. Annealing or stress relieving will also remove internal stresses that build up from excessive machining. This can increase material stability for further heat treating or working. With our large carbottom furnaces we can atmosphere anneal with nitrogen up to a temperature of 1450°F and 35000 lbs.




		Vacuum Annealing When a material needs to be softened and keep a bright finish, vacuum annealing is used. Vacuum annealing or bright annealing is used to improve formability and machinability through the reduction in internal stresses and improved microstructural characteristics. Finished parts can be annealed using this process without worry of damage to its appearance.




		Carburizing Carburizing is a process where a material is heated above its transformation temperature and introduced to a carbon rich atmosphere. The carbon is diffused into the material forming iron nitrides and upon quenching, a hard surface layer is formed. This is usually done in a temperature range from 1600°F - 1750°F and can produce case depths of 0.020" plus. The temperature and carbon potential is precisely controlled using micro processing controllers that allow for accurate case depth formation.




		Neutral Hardening In order to achieve the correct measures of hardness, strength, and ductility, metals are often required to be hardened and tempered. Our batch hardening furnaces operate in a range of 1400°F - 1800°F with an oil quench in either a still or agitated state at 150°F - 225°F. Our tempering furnaces range from 300°F - 1200°F depending on the desired mechanical properties. We have the capability to incorporate special fixtures and racking to allow parts to be separated or oriented in a desired manor.




		Ferritic Nitrocarburizing Ferritic nitrocarburizing is a case hardening process that produces an extremely hard surface layer that improves wear life and aides in lubricity and corrosion resistance. Since the process is carried out at relatively low temperatures and without the need for quenching, it shows negligible shape changes and leaves a good surface finish. We can produce case depths of 0.0002" - 0.001" at temperatures ranging from 925°F - 1100°F.




		Zinc Phosphate Coating Our high volume immersion coating line is capable of producing zinc phosphate base coatings in the range of 500 mg/ft² - 2000 mg/ft² with either a polymer based lubricant or dry-to-touch oil surface coating. We have both racking and barrel capabilities.
