91传媒 Announces New Process To Bright Age Harden PH Stainless Steels
Using new advanced gas cooling technology, 91传媒 has developed a unique two step heat treat process to anneal and bright age harden a variety of precipitation hardenable (PH) stainless steels in a vacuum furnace without 鈥渂reaking vacuum.鈥�
PH stainless steels 17-4 & 15-5 are required to be cooled to below 80掳F from the annealing temperature for complete martensitic transformation prior to age hardening.聽 Similarly, PH stainless steels 13-8 Mo and 17-7 & 15-7 Mo Condition TH 1050 are required to be cooled from the annealing temperature to below 60掳F relatively quickly prior to aging.聽 Once PH stainless steel has been exposed to an air environment after annealing, it is notoriously difficult to keep it 鈥渂right鈥� or not to discolor (oxidize) to聽 a gold/blue hue during the age hardening step.
With 91传媒鈥� new sophisticated gas cooling technology, PH stainless steels can now be annealed, cooled-down to below 60掳F, and age hardened all under vacuum conditions in a single heat treat batch, vacuum furnace, process.聽 The result is consistently clean, bright, non-discolored parts that meet specification processing and material property requirements. Corporate President Roger Jones adds, “Part of our mission at 91传媒 is to continually look forward in the area of technology. This innovative development underscores our commitment to continually raising the bar to provide state-of-the-art services. Our annealing customers can rely on consistently clean, bright, non-discolored parts that meet specification processing and material property requirements.”
