In continuous annealing, accelerated cooling methods have recently found practical application in addition to conventional gas jet cooling or water jet quenching method. Moderate cooling rate of gas jet cooling or accelerated cooling makes it possibles to utilize new high-strength steels with excellent properties. The faster cooling rate deteriorates ductility of steels. These newly developed steels are improved rephosphorized steels with high r-value and high bake hardenability, dual phase steels with superior ductility, Ti-stabilized high-strength steels with very high r-value, grain boundary hardening steels employing low temperature annealing, and unique ultra high-strength steels. This paper describes properties and process factors of these steels, and their applications to automotive. (Wassmann)
