摘要
PROBLEM TO BE SOLVED: To provide a high strength wire rod excellent in forgeability, under head toughness as a bolt, and a delayed fracture resistance, and having tensile strength of 1,200 N/mm2, and to provide a useful method for producing the same high strength wire rod. ;SOLUTION: This wire rod is composed of steel containing 0.50 to 1.0% C, and in which the content of Si is suppressed to 0.1% as well, and, by suppressing the formation of one or more kinds of structures among pro- eutectoid ferrite, pro-eutectoid cementite, bainite and martensite, the area ratio of a pearlitic structure is controlled to 80%, and also, by forced wire drawing, strength of 1,200 N/mm2 and excellent delayed fracture resistance are imparted thereto.;COPYRIGHT: (C)2001,JPO
