Rapid heating makes austenite grain of steel finer than usual heating. Study of application of rapid heating to lead patenting of high carbon steel wire rods has been done. After high carbon steel wire rods are rapidly heated and held for short time, they were quenched in oil. High carbon steel wire rods were rapidly heated again followed by cooling in a lead bath. The various properties of wire rods treated described above have been examined. Wire rods rapidly heat patented in this process are superior to usual lead patented ones in the following points. (1) Austenite grain of rapidly heated wire rods is finer than that of usually heated ones. (2) Lead bath temperature in patenting for rapidly heat treated wire rods is lower than that for usually heat treated ones. (3) Tensile and fatigue strength of rapid heat patented and drawn wires is higher than those of usual patented ones. (4) Drawability and bending properties of rapid heat patented and drawn wire is better than these of usual patented ones.
