This paper will present the advantages and disadvantages of quenching media options like HPGQ (high pressure gas quenching), Oil and Press Quenching, Austempering (salt) for steel, ADI (austempered ductile iron) and aluminum to achieve certain targets relating to automotive component heat treating. Each heat treating/quenching process provides unique solutions for automobile designers and plant engineers. However, there likely is no single process or material that provides all of the answers that one would desire. Therefore, what process or combination of processes will satisfy the overall need? Detail will be discussed that outlines how OEM’s and heat treaters can and do take advantage of a particular hardening process.
