A bushingless track pin is disclosed. The track pin includes a hardened outer layer and a relatively softer inner core. The track pin may be formed using high carbon steel, which in some cases may be substantially spheroidal martensite crystal structure. A track pin may be formed using the high carbon steel, followed by a hardening process. In some examples, an optional induction hardening process may thereafter be performed on the inner surface most proximal to the central hole of the track pin if needed. The hardening on the inner surface may harden the outer portion while tempering the core portion of the track pin.
