Abstract
PURPOSE:To obviate the degradation in elongation percentage owing to N aging and C aging by regulating the content of N, and controlling the heating and coiling temps. of the slab in a hot rolling stage to prescribed temps. CONSTITUTION:A continuously cast killed steel slab consisting, by weight, of 0.03-0.15% C, <=0.35% Si, <=0.8% Mn, <=0.1% P, <=0.02% S, 0.01-0.1% Al and the balance Fe as basic componets, and further regulated to <=0.002% N is rolled as follows: The slab of the above-mentioned composition is hot rolled under controlling to <=1,200 deg.C heating temp., after which it is coiled under controlling to <=50 deg.C coiling temp. In some cases, Ti is contained within the range of <=0.02% Ti and Ti/N>=3.5 other than the above-described basic composition.
