Aerospace Company Orders Nitriding System
Nitrex Metal shipped a four-in-one combination nitriding system to an aerospace company for the start-up phase of a new production line of stainless steel and nitralloy gears. The system combines four different technologies that include Nitreg® potential-controlled nitriding, Nitreg®-S for nitriding stainless steels, Nitreg®-C ferritic nitrocarburizing and ONC® for in process post-nitriding/nitrocarburizing oxidation. The ability to perform all treatments in one furnace and the possibility to nitride with tightly controlled white-layer thickness, including a deep case with zero white layer, were the main reasons Nitrex was chosen for this project.
The system features a top-loading furnace with a 660-pound capacity, a fully automatic control system with an ammonia sensor for early leak detection, a chart recorder, an ammonia dissociator and special racking used solely for performing a 9-point temperature uniformity survey in accordance with ASM 2750.
