Abstract:
This H section includes, as a chemical composition, C, Si, Mn, Nb, V, Ti, and N; in which the H section includes, as a metallographic structure, ferrite of 60 area % to less than 100 area %, an average grain size of this ferrite is 1 μm to 30 μm, a thickness of a flange is 20 mm to 140 mm, tensile yield stress is 385 MPa to 530 MPa, and Charpy absorbed energy at −20° C. is 100 J or more.

Claim (Index 7):
A method for manufacturing the H section according to  claim 1 , comprising:\n steelmaking to obtain a molten steel which has the chemical composition according to  claim 1 ; casting the molten steel after the steelmaking to obtain a steel piece; heating the steel piece after the casting to 1,100\u00b0 C. to 1,350\u00b0 C.; hot rolling on the steel piece after the heating to form a shape, when being seen in a cut section orthogonal to a rolling direction, into an H-shape under conditions, wherein\n a cumulative rolling reduction at a position of (1/6)F from an end surface of a flange in a width direction within more than 900\u00b0 C. and 1,100\u00b0 C. or less is 20% or more, \n the cumulative rolling reduction at the position within 730\u00b0 C. to 900\u00b0 C. is 15% or more, and \n the rolling ends at 730\u00b0 C. or more; and \n cooling a hot rolled material after the hot rolling by natural cooling.
