Abstract

Provided is weathering steel which is preferably used as a structural steel material in an environment where a temperature is high and a dry period during which rain fall is small such as a dry season exists. The weathering steel has the component composition which contains C, Si, Mn, P, S, Al, Cu, Nb, Sn and a balance constituted of Fe and unavoidable impurities. The weathering steel satisfies at least either one of the following formulae (1) and (2), and also satisfies the following formula (3). (Cu-0.01) x (Sn-0.005) x (Nb-0.005) x 104 ? 0.08 (1), (Cu-0.01) x (Ni-0.01) x (Cr-0.01) x 50 ? 0.08 (2), (Cu+l0xSn) / (2xNi+0.5xSi) <10 (3). The weathering steel also contains, when necessary, one or more kinds of elements selected from a group consisting of Ni, Cr, Mo, W, Co, Sb, Ti, V, Zr, B, REM, Cu, Mg. Here, respective element symbols represent the contents of the elements (mass%), and an element not contained is made zero.
