Premium 5/16″ X 1″ X 18″ Starrett Oversize Precision Ground Flat Stock AISI D-2 Air Hardened Steel 69413

5/16″ X 1″ X 18″ Starrett Oversize Precision Ground Flat Stock | AISI D-2 Air Hardened Steel | 69413 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.

High carbon, high chromium tool steel provides superior wear resistance and edge retention compared to standard steel stocks

Air hardened steel offers uniform hardening characteristics and dimensional stability during subsequent machining

Precision ground faces deliver consistently flat surfaces for accurate fixturing, gauging, and secondary machining

Oversize stock enables final machining to exact final dimensions with minimal material waste

Suitable for tooling, die work, and precision fabrication where flat stock with stable dimensions is required

Machining note: tougher material; carbide tooling and appropriate feeds/speeds recommended for efficient cutting
