Zusammenfassung:	To provide a shock resistance wear component excellent in durability, and a method for manufacturing the same.SOLUTION: A ripper shank 10 served as a shock resistance wear component consists of steel having a hardness of 53 HRC or more and 57 HRC or less and having a specific component composition. The steel includes: a parent phase including a martensitic phase and a retained austenite phase; and first nonmetal grains dispersed in the parent phase and including at least one kind selected from a group consisting of MnS, TiCN and NbCN. The steel does not include M23C6 carbide.SELECTED DRAWING: Figure 3 【課題】耐久性に優れた耐衝撃摩耗部品およびその製造方法を提供する。【解決手段】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、Ｍ２３Ｃ６炭化物を含まない。【選択図】図３
