Abstract
(EN)
Provided is a steel material having a metal composition in which hard particles having a hardness of 1100 HV or higher are dispersed after a heat adjustment process, the area ratio of the hard particles having an equivalent circle diameter of 0.5 μm or higher in a cross-section being 1.0% or higher.
(FR)
L'invention concerne un matériau d'acier ayant une composition métallique dans laquelle des particules dures ayant une dureté supérieure ou égale à 1100 HV sont dispersées après un processus de réglage de la chaleur, le rapport de surface des particules dures ayant un diamètre de cercle équivalent supérieur ou égal à 0,5 µm dans une section transversale étant inférieur ou égal à 1,0 %.
(JA)
調質熱処理後に硬さが1100HV以上の硬質粒子が分散した金属組織を有し、断面における円相当径0.5μm以上の前記硬質粒子の面積率が1.0%以上である鋼材を提供する。
