Starrett 57564 A2 Tool Steel Flat Stock 5/32x2x18 in

Product Description

The STARRETT 57564 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, fixture building, and precision machining applications. Measuring 5/32 inches thick, 2 inches wide, and 18 inches long, this flat stock ships in an annealed condition ready for machining and subsequent air-hardening heat treatment. A2 tool steel offers good dimensional stability during hardening and a balanced combination of wear resistance and toughness, making it a reliable choice for punches, dies, gauges, and cutting tools. Weight is approximately 1.6 pounds per piece.

This flat stock is suited for job shops, tool and die shops, and maintenance departments that fabricate or repair tooling in-house. The 18-inch length provides enough material for a range of small-to-medium tool blanks. The flat bar geometry simplifies layout and reduces initial stock removal compared to round or square bar. Licensed machinists and toolmakers typically work this material on mills, surface grinders, and EDM equipment before hardening and tempering to final hardness.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel working procedures. Follow the material manufacturer guidelines for annealing, hardening, and tempering temperatures specific to A2 tool steel. All grinding and cutting operations should be performed with appropriate coolant to prevent surface damage. Handle flat stock carefully to avoid nicks or bends that may cause stress concentrations in the finished tool.
