Abstract
PURPOSE:To produce a steel plate having desired yield strength and having a low yield ratio and good toughness in combination by heating a steel specified in the contents of C, Si, Mn, and V to a specific temp. range and hot rolling this steel, then subjecting the steel to reheating, water hardening and tempering after rapid cooling. CONSTITUTION:The steel consisting, by weight, 0.05-0.20% C, 0.05-0.75% Si, 0.30-2.20% Mn, 0.001-0.100% V, 0.005-0.080% solAl, <=0.01% N, and the balance Fe and inevitable impurities is smelted and is made into a slab. This steel slab is heated to 1,000-1,250 deg.C and is hot rolled; in succession, the steel plate is rapidly cooled at >=2.5 deg.C/sec cooling rate in the central part of the plate thickness from the Ar3 point or above. The steel late is then reheated to an Ac1-Ac3 temp. range and after the plate is water-hardened, the plate is tempered down to the temp. below the Ac1 point or below. One or more than one kinds of Cu, Ni, Cr, Mo, Nb, B, and Ti are incorporated at adequate ratios at need into this steel compsn. The high tensile steel plate for buildings which is applicable to high-rise buildings and has less residual stresses is thereby stably produced.
