Title (EN) HIGH-STRENGTH WIRE ROD EXCELLING IN WIRE DRAWING PERFORMANCE AND PROCESS FOR PRODUCING THE SAME
(FR) TIGE D’ENROULEMENT HAUTEMENT RÉSISTANTE PRÉSENTANT D’EXCELLENTES PERFORMANCES D’ÉTIREMENT DE CÂBLES ET SON PROCÉDÉ DE PRODUCTION
(JA) 伸線特性に優れた高強度線材およびその製造方法
Abstract:
(EN) A wire rod composed mainly of pearlite either having a cross section wherein the average of area ratio of non-pearlite structures consisting of pro-eutectoid ferrite, pseudopearlite and bainite is 5% or below, or having a portion extending from the surface layer to a depth of up to 100 μm wherein the average of area ratio of non-pearlite structures is 10% or below, which high-strength wire rod is produced by subjecting a hard steel wire rod of specified components to hot rolling and thereafter either direct molten salt patenting or re-austenitizing and subsequent molten salt or lead patenting.
(FR) La présente invention concerne une tige d’enroulement principalement composée de perlite soit dont la section transversale présente un rapport d'aire moyen de structure non perlite constitué de ferrite pro-eutectoïde, de pseudo-perlite et de bainite inférieur ou égal à 5%, soit comportant une portion s’étendant depuis la couche de surface vers une profondeur pouvant atteindre 100 µm, le rapport d'aire moyen de structure non perlite étant inférieur ou égal à 10%, laquelle tige d'enroulement hautement résistante étant produite en soumettant une tige d'enroulement d'acier dur de composants spécifiques à un laminage à chaud et ensuite soit à un patentage direct au sel fondu, soit à une ré-austénisation et à un patentage consécutif au sel fondu ou au plomb.
(JA)  成分の特定された硬鋼線材を、熱間圧延後に直接溶融ソルトパテンティング処理すること、もしくは再オーステナイト化後溶融ソルトもしくは鉛パテンティング処理することにより得られる、パーライトを主体とし、断面内の初析フェライト、擬似パーライトもしくはベイナイトからなる非パーライト組織の面積率の平均値が5%以下である、もしくは表層から100μmまでの深さの部分において、非パーライト組織の面積率の平均値が10%以下であるような線材。
