It is well known that rolling procedure considerably affects microstructures and mechanical properties of steels used in hot-rolled condition. The properties of Si-Mn steels treated under various rolling and cooling conditions have been studied from the standpoint of the refinement of austenite and ferrite grain. The present results show that low heating and finishing temperatures and adequately controlled cooling rate are necessary to obtain finer ferrite-pearlite microstructures, and that these refinements are affected by the total reduction, ratio rather than the amount of one pass reduction.
