Abstract
PURPOSE: To provide a high-strength hot-rolled steel plate having superior flash butt weldability and cold workability and contg. a predetermined percentage of ≥1 kind of C, Mn, si, Nb, V and Ti and/or Zr and bainite structure by a specified percentage by area or more.
CONSTITUTION: The titled hot rolled steel plate contains 0.01W0.12% C, 1.0W 3.0% Mn and 0.01W1.5% Si and further contains 0.01W0.1% Nb as a precipitation hardening element, 0.02W0.2% V maintaining the hardness of the weld zone and ≤0.25% in total of 0.01W0.1% Ti and/or 0.02W0.2% Zr as elements fixing N in the steel, and the plate essentially contains bainite structure by ≥60% by area. By heat treating the above-mentioned steel in accordance with the composition, bainite structure is formed to obtain the steel plate having high flash butt weldability and cold workability required as properties of a material for a wheel rim, a disc, etc.
