Companies are now expected to be able to lower recalls and warranty costs with a new Automotive Industry Action Group guideline that monitors parts undergoing heat treatment. Heat treatment is a special process that improves strength, fatigue life, ductility, wear and corrosion resistance on parts like seat belts and steering gears. The guideline defines the fundamental requirements for this process, because improper heat treatments result in one or more recalls a year and higher warranty costs.

The 71-page guideline was developed by original equipment manufacturers, part suppliers and heat-treat service suppliers, and outlines the key elements of a heat treat assessment. For more information, visit www.aiag.org/press/releases/GENERAL/PR_heatreat_finalWeb.pdf.
