Through hardened steel spur gear

A single steel spur gear shown as a solid metallic gray component with uniform coloration and material appearance across the entire body, tooth depth, and core, indicating consistent through-hardening rather than a hardened outer case. The gear is circular or cylindrical with evenly formed straight machined involute teeth around the perimeter, a central circular bore, crisp tooth edges, smooth machined faces, and no visible coating, layered shell, or surface-only treatment. Industrial clipart-style presentation, optionally in slight three-quarter view, with a clean machined finish.
