Steel Material For Sliding Components And Production Method For Steel Material For Sliding Components

Abstract: Provided is a steel material for sliding components that has excellent sliding properties and workability. The steel material for sliding components: comprises a steel material having 0.30%–0.60% by mass C content; has a structure that includes iron carbide and at least either tempered martensite or bainite; has a total, by volume fraction, of at least 80% tempered martensite and bainite and at least 2.0% iron carbide; and has a Vickers hardness Hv of 300–600. The volume fraction X of the iron carbide and the Vickers hardness Hv fulfill the relational expression (1). X = –0.065 × Hv + 36.5 (1). The unit for X is % and the unit for Hv is Hv.
