Uniaxial and biaxial torsional fatigue tests were conducted on the specimens extracted from urban railway wheel steel. The ultimate and yield strengths of the steel were 1027.7 MPa and 626 MPa, respectively. The uniaxial fatigue limit was 422.5 MPa, which corresponds to 67% of the ultimate tensile strength. The ratio of e e τ<SUB>θ</SUB> /σ<SUB>θ</SUB> was 0.63. The fatigue strength coefficient and exponent were 1319.5 MPa and 0.339, respectively. The maximum principal and equivalent strain were found to be adequate parameters to predict the fatigue lifetime of the steel under a multiaixal fatigue condition.
