CONSTITUTION:Steel consisting of 0.01-0.12 C by %, 0.5-1.2 Mn, 0.10-0.25 Si, 0.001-0.030 P, <=0.010 S, 0.0010-0.0060 Ca, and the balane Fe with unavoidable impurities is completed of hot rolling at 80-840 deg.C, is cooled at 5-15 deg.C/sec in excess of 700 deg.C, is quickly cooled at >=15 deg.C/sec to below 700 deg.C and is coiled at below 570 deg.C. Here, low temp. toughness degrades with all of the C above the upper lumit, the Mn out of the range, the S above the upper limit, and the Ca below the lower limit. The hot rolling outside said range results in degraded low temp. toughness. The cooling rate in excess of 700 deg.C is the range where the low temp. toughness is improved. The coiling temp. provides good low temp. toughness as well under the above-described conditions.
