Description
5/16" X 3" X 18" Starrett Precision Ground Flat Stock | AISI D-2 Air Hardened Steel | 69170 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi d-2 air hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.
- Precision ground edges and faces for square, repeatable setups in milling, drilling, and slotting operations.
- High wear resistance and edge retention from AISI D-2 tool steel; suitable for repeated stamping, blanking, and forming tasks.
- Flat stock form provides a ready-to-machine base for fixtures, gauges, and die components.
- Air hardened profile enables strong, stable performance without oil hardening; compatible with standard heat treatment workflows to tailor hardness after fabrication.
- Non-stainless steel; store in a dry environment to minimize corrosion risk.
