Starrett 57613 A2 Tool Steel Flat Stock 0.5x10x18 in

Product Description

The STARRETT 57613 is an A2 air-hardening tool steel flat stock blank used in toolmaking, die making, and precision machining applications. Measuring 0.5 inches thick, 10 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances: +0.010 to 0.015 inches on thickness, width, and squareness, and +0.25 inches on length. A2 tool steel offers good toughness, wear resistance, and dimensional stability during heat treatment, making it a reliable choice for dies, punches, gauges, and forming tools that require air-hardening heat treat cycles.

This flat stock is suited for job shops, tool and die shops, and in-house maintenance departments fabricating or reconditioning tooling components. The 10-inch width and 18-inch length provide sufficient material for medium to large die sections, forming blocks, or blanks that will be rough-machined before hardening. The air-hardening A2 grade reduces distortion risk compared to oil-hardening grades, making it a common specification when close final tolerances must be held after heat treatment.

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock blank suitable for use in tool and die fabrication, punch press tooling, and precision machining applications where AISI A2 material specification is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with AISI air-hardening grades. Follow the material manufacturer's recommended preheat, austenitizing, and air-quench procedures to achieve target hardness and minimize distortion. Always use appropriate personal protective equipment when cutting, grinding, or heat treating tool steel stock. Consult applicable shop safety codes and material data sheets before beginning any heat treatment operation.
