Abstract

PURPOSE: To produce a titled steel which makes the reduction in carburizing time or the like possible by heating a continuously cast ingot contg. C, Si, Mn, Al as well as one or more kinds of Ti, Zr and Hf, and N respectively at specified ratios, to a high temp. then rolling or forging the same.
CONSTITUTION: A continuously cast ingot of a steel which contains 0.12W0.03% C, 0.1W1.0% Si, 2(C%)W2.5% Mn, and 0.01W0.05% Al as well as one or more kinds of Ti, Zr and Hf, and contains 0.01W0.05% (Ti%)+0.53(ZR%)+0.27 (Hf%), and 0.015% 0.29(Ti%)+0.15(Zr%)+0.08(Hf%) N, respectively is prepd. Next, this ingot is heated to below 120°C or above 1,300°C, after which it is stretched by rolling or forging, whereby the steel for machine structural use for forging having still fine structure at high temps. is produced. This steel makes it possible to omit direct annealing after hot forging and normalizing after hot forging or to reduce carburizing time and permits saving of energy in secondary working process.
