Aluminum Killed Steel - an overview ScienceDirect Topics

A FRT in fully austenitic region is preferred in CA-aluminum killed steels as well. Coiling temperature (CT) Unlike BA-AK steels, higher CT is used in CA process to fix nitrogen with aluminum during the coiling stage itself and thus solute nitrogen is no longer available to affect the grain growth process during recrystallization annealing. Austenitic Grain-Size of Steel MetallurgyTable 2.6 compares effects of grain size on the properties of the materials. Now-a-days, steels are supplied to grain size specifications. As fine-grained materials have better room temperature strength, ductility, toughness and other properties, thus, many heat treatments are carried out to obtain fine-grain
