Applied Process, Inc. along with Ajax Tocco Magnethermic Corp., ThyssenKrupp Waupaca, Inc., and Linamar Corp. offer a new surface austemper heat treatment process called Locally Austempered Ductile Iron (LADI).
- Induction based heat treatment process allows localized regions of a cast iron components to be austempered
- Reportedly improves wear properties and contact fatigue strength over similar surface hardening heat treatments
- Developed utilizing unalloyed grades of ductile iron allowing for reduced casting cost and increased machine tool life
- Validated as a material process combination for automotive camshafts; powertrain components, gears, ground engaging equipment, wear surfaces could also benefit
