Abstract

PURPOSE: After a steel material comprising specific quantities of C, Si, Mn, P, S, Cu, Al and Fe is subjected to rolling and finial finishing at above 850°C by a hot hot strip mill, it is coiled at above 670°C, whereby the captioned hot coil material whose strength level is equivalent around API standard ×42W×70 is produced.
