Abstract

Austenite continuous cooling transformation diagram for electric steel C80D2 microalloyed with boron and vanadium is constructed. The effect of cooling rate and heat of phase transformations on perlite dispersability is shown. Theoretically substantiated regime of C80D2 steel rolled wire cooling on Stelmor line is developed.
