Conclusions
Quenching and tempering of cast ferritic — pearlitic steels refines the grains and makes it possible to increase the yield strength and the stress at which crack formation begins with almost no change in hardness, to improve the ductility and toughness at positive and negative temperatures, and to increase the fatigue limit of the steel.
