As heat treaters, we are always looking for ways to shorten our processing times. Increasing carburizing temperature has long been known to shorten cycle times, but grain growth has been our Achilles’ heel. Today there is renewed focus on optimization of diffusion-related processes, and certain microalloying elements show promise for allowing us to raise carburizing temperatures. Let’s learn more.
Check out the May 2017 issue of Industrial Heating, which includes features on Ford's $1.2 billion investment in three Michigan facilities, a roundup of heat-treat process-verification articles, and much more.
