The CTS Series offers multiple component configurations allowing them to be used for either vacuum operation, pressure operation, alternating vacuum pressure operations and in low flow applications. Hargraves has a wide range of part numbers in this series to assist you in your application.
The treatment takes place at low pressure. The depression is maintained by the vacuum pump units while the injection of the nitriding mixture is controlled by mass flow meters. The nitriding working temperatures are standard; they are between 400 and 600°C.
