3/8″ X 8″ X 18″ Starrett Precision Ground Flat Stock AISI A-2 Air Hardened Steel 59133 High Quality

3/8″ X 8″ X 18″ Starrett Precision Ground Flat Stock | AISI A-2 Air Hardened Steel | 59133 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi a-2 air hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.

Precision ground flat stock delivers consistent flatness and squareness across all faces

AISI A-2 air hardened tool steel combines wear resistance with good dimensional stability during forming and machining

Air hardened design minimizes distortion during heat treatment and supports repeatable tooling performance

Machinable with standard carbide or high-speed steel tooling for drilling, milling, and grinding operations

Ideal for fixtures, dies, blades, and prototype tooling where dimensional accuracy is critical
