Heat Treating Iron Components
Some iron castings, depending on the application, require heat treating. Stress relieving or annealing to soften, are the processes used in house. Northern Iron and Machine utilizes specialized annealing ovens for this process. Where hardening is required, proven outside contractors are utilized.
Also available are additional heat treating processes to provide increased part strength and yield while reducing part elongation. Among these processes are normalize & temper, quench & temper, and austemper.
