Abstract
PURPOSE: To obtain titled high-tensile steel permitting additional intensification by making the temp. for stopping of the accelerated cooling after heating-rolling under adequate conditions for steel of composition having adequate content of Nb lower than that in the prior art.
CONSTITUTION: A slab of 0.02W0.15 C, by %, 0.03W0.60 Si, 1.0W2.5 Mn, 0.005W 0.060 solAl, 0.01W0.10 Nb, ≥1 kinds of limited amts. of Ti, Ni, Cu, Mo, V, Cr, B, Ca, REM and ≤0.008 S and F out of the balance unavoidable impurities is heated to 1,180°C or below temp. at which Nb solutionizes at ≥0.01. Thereafter, it is rolled to ≥ 50% cumulative draft in an austenite recrystallization temp., in succession to which it is rolled to ≥50% cumulative draft at Ar3WAr3+150°C. Thereafter, it is cooled immediately down to 450W300°C at 2W20°C/sec. cooling rates, after which it is air-cooled. With the accelerated cooling temp. in excess of the upper limit, the two phase structure of ferrite and bainite is formed, and the effect of increasing strength is not large. Below the lower limit, the amt. of martensite increases and this decreases the effect of tempering.
