Abstract

Provided are a hot-rolled steel sheet for a magnetic pole having high strength and excellent welding properties and magnetic characteristics, a method for manufacturing the same, and a rim member for hydroelectric power generation. The present invention comprises 0.02% to 0.12% of C, 0.1% to 0.7% of Si, 0.8% to 1.6% of Mn, 0.03% or less of P, 0.005% or less of S, 0.08% or less of Al, 0.006% or less of N, and 0.06% to 0.20% of Nb, the remainder comprising Fe and unavoidable impurities. In the present invention, a ferrite phase accounts for 98% or more in terms of area ratio, the amount of precipitated Fe is 0.22% by mass or less with respect to the amount of Fe included in the steel, the amount of precipitated Nb is 80% by mass or greater with respect to the amount of Nb included in the steel, the average particle diameter of carbides including precipitated Nb is 6 nm or less, the yield strength in the direction of rolling in 500 MPa or greater, the magnetic flux density B50 is 1.4 T or greater, the magnetic flux density B100 is 1.5 T or greater, and the minimum value of the Vickers hardness of a welding-heat-affected zone is equal to at least the average value of the Vickers hardness of the base material minus 30.
