Abstract

Steel for a vehicle wheel containing C in an amount of O.65 to 0.84%, Si in an amount of 0.4 to 1.0%, Mn in an amount of 0.50 to 1.40%, Cr in an amount of 0.02 to 0.13%, S in an amount of 0.04% or less, and V in an amount of 0.02 to 0.12%; Fnl in the formula Fnl=2.7+29.5xC+2.9xSi+6.9xMn+10.8xCr+30.3xMo+44.3xV being 32 to 43; Fn2 in the formula Fn2=exp(0.76)xexp(0.05xC)xexp(1.35xSi)xexp(0.38xMn)xexp(0.77xCr)xexp(3.0xMo)xexp(4.6xV) being 25 or less; the remainder comprising Fe and impurities; and the amounts of P , Cu, and Ni contained in the impurities being 0.05% or less, 0.20% or less, and 0.20% or less, respectively. This steel has an exceptional balance between wear resistance, rolling fatigue resistance, and spalling resistance, while also having exceptional high -temperature yield strength and high ductility.
