Abstract

PURPOSE:To efficiently manufacture a more rapidly spheroidizable steel material by working a steel having a specified compsn. at a specified working rate in a temp. range below the recrystallization temp. of austenite and by cooling the resulting steel material under specified conditions. CONSTITUTION:A steel consisting of, by weight, 0.10-2.00% C, 0.10-1.50% Si, 0.10-2.50% Mn, <=0.12% S and the balance Fe or further contg. one or more among 0.10-2.00% Ni, 0.10-15.00% Cr, 0.10-3.00% Mo, 0.10-19.00% W and 0.10-2.20% V is heated to the Ac3 or Accm point or above and hot worked. During this hot working, the steel is worked at 10-80% working rate in a temp. range below the recrystallization temp. of austenite in at least the finishing stage. The resulting steel material is cooled to a temp. range just above the Ms point at 1.5-100 deg.C/sec cooling rate.
