Heat Treat

With a 10,000-square-foot expansion of our heat treating facility, Overton Chicago Gear provides unrivaled capacity and capability to heat treat gears up to 90" in diameter. Our newest additions include two state-of-the-art carburizing systems that employ the latest U.S. and European technologies, along with an 84-inch quench press possibly the largest in the world.  

Our heat treating facility offers annealing, normalizing, carburizing, nitriding, hardening, quench and tempering. We also have shot peening and shot blasting capabilities. 

Each furnace is computer-controlled for temperature and atmosphere. To ensure the highest quality, we continuously monitor all elements of the process for computer-controlled auto adjustments. This is verified in our modern state-of-the-art metallurgical laboratory where samples from each load are analyzed and accurately recorded.
