Abstract
PURPOSE: To provide a hot rolled steel plate for a wheel disc with improved molding property and fatigue characteristics by a method wherein a specific amount of C, Mn, Si, Cr or the like is contained in Fe and a steel structure thereof is formed into polygonal ferrite or bainite with a specified area ratio.
CONSTITUTION: A hot rolled steel plate for a wheel disc comprises steel containing 0.01W0.15% C, 0.8W2.5% Mn, 0.01W1.5% Si, 0.01W1.5% Cr and, if necessary, containing Nb, V, Ti, Zr, Mo, B, Ni, Cu, P, Ca, Mg, REM added thereto auxiliary. By this steel composition and predetermined hot rolling and cooling treatment, the hot rolled steel plate for the wheel disc having structure comprising polygonal ferrite and bainite of which an area ratio of the bainite is 5W60% and having improved balance of strength-elongation and excellent in elongation flange property is obtained.
