The process temperatures for our PVD coatings can range from 385°F-750°F depending upon the particular coating being deposited. Please note that we recommend draw temperatures of 750°F+ in order to avoid distortion or hardness changes. If these draw temperatures are not possible for your parts, then we recommend you contact us for special instructions in order to provide for the safe processing of your parts. The process temperature for CVD coating will reach 1925°F; therefore, any tool steels or HSS being CVD coated will be annealed during coating. After coating, we will vacuum heat-treat all steels in order to achieve the customer’s required hardness. The process temperature for TD coating will generally be about 1650°F; therefore, any tool steels or HSS being TD coated will be annealed or partially annealed during coating. After coating, we will vacuum heat-treat all steels in order to achieve the customer’s required hardness.
