Abstract
(EN)
A ripper shank (10), being an impact- and wear-resistant component, comprises steel having a specific composition and having a hardness of 53–57 HRC. This steel includes: a matrix phase comprising a martensite phase and a residual austenite phase; and first non-metallic particles dispersed in the matrix phase and including at least one type selected from the group consisting of MnS, TiCN, and NbCN. The steel does not include an M23C6 carbide.
(FR)
Une tige de défonceuse (10), qui est un composant résistant aux chocs et à l'usure, comprend de l'acier ayant une composition spécifique et ayant une dureté de 53 à 57 HRC. Cet acier comprend : une phase de matrice comprenant une phase de martensite et une phase d'austénite résiduelle ; et des premières particules non métalliques dispersées dans la phase de matrice et comprenant au moins un type choisi dans le groupe constitué de MnS, TiCN et NbCN. L'acier ne comprend pas de carbure M23C6.
(JA)
耐衝撃摩耗部品であるリッパシャンク(10)は、硬度53HRC以上57HRC以下の特定の成分組成の鋼からなる。この鋼は、マルテンサイト相と、残留オーステナイト相とを含む母相と、母相中に分散し、MnS、TiCNおよびNbCNからなる群から選択される少なくとも1種を含む第1非金属粒と、を含み、M23炭化物を含まない。
