Abstract
PURPOSE: Continuously casted materials or large steel ingots larger than determined size in thickness consisting of the each specified amount of C. Si. Mn. P. S and remainder Fe and alloying elements are tempered subsequent to rolling. Thereby the increase of hardness, decrease of toughness and occurrence of cracks are prevented.
