摘要

The steel for forgings according to the present invention is characterized in that the steel contains, by mass%, C: 0.28% to 0.47%, Si: 0% to 0.45%, Mn: 0.90 to 1.50% More than 0% to 0.30% or less, Mo: more than 0% to 0.15% or less, and V: 0.06% or more to 0.32% or less and the remainder being iron and inevitable impurities, is a total area ratio of not less than 90%, the equivalent circle diameter and the number density of at least 55 / μm ² 500 gae / μm ² or less of the pro-eutectoid ferrite of V-carbides than 50nm, yield stress of at least 420MPa, fatigue The strength is more than 330 MPa. Thus, excellent workability, high yield stress and high fatigue strength can be realized.
