Abstract

PURPOSE: To provide high strength and toughness only with primary cooling of forged product without thermal refining of quenching and annealing by adding V, N, and other elements of forging steel.
CONSTITUTION: A forging steel composition contains C: 0.30W0.60%, Si: 0.60W 1.20%, Mn: 0.60W1.20%, V: 0.03W0.20%, sol. Al: 0.02W0.06%, N: 0.008W 0.02%, into which, as required, Cr<0.5% and further one or more of S<0.13%, Pb<0.30%, Ca<0.01%, Se<0.10%, Te<0.10%, Bi<0.10% and Ce<0.20% are added as single elements or compounded with Cr. V and N contained in this forging steel causes carbon nitride to precipitate, which acts as nucleuses for ferrite transformation. Thus, steel base becomes fine ferrite pearlite structure to provide a high strength and toughness, as forged, without thermal refining treatment.
