Abstract

PURPOSE:In low carbon steel containing an adequate amount of Cu, Mn and the like, a hot-rolling condition is specified on rolling temperature, processing quantity, cooling rate and others, to provide material as rolled with the same mechanical property as when thermal refining is conducted. CONSTITUTION:A low-carbon steel and like material containing C:0.25-0.6% and Mn:1.5% or less, is rolled at a rolling temperature of 850-1050 deg.C, in a processing quantity of 30% or higher and a final finishing temperature of 850-950 deg.C, and cooled at a normal rate of 0.3-5 deg.C/sec. The above-described composition for low- carbon steel and condition for rolling provide rolled material having structure with pearlite colony of finer grain No.6 or higher, compared with conventional grain of No.4-5 or so. The process while eliminating annealing operation, provides low-carbon steel and the like with an enhanced machanical property, particulary yield- strength ratio, ductility and toughness together with machinability and cold-process property.
