Starrett 54675 A2 Tool Steel Flat Stock 5/8x2x36 in

Product Description

The STARRETT 54675 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die-making, and precision machining applications. Measuring 0.625 inches thick, 2 inches wide, and 36 inches long, this flat stock is ground to tight tolerances, making it suitable for applications where dimensional consistency is critical. A2 tool steel offers good toughness and wear resistance with minimal distortion during air hardening. The piece weighs 14.66 pounds and is manufactured to AISI A2 material specification. Machinists, tool and die makers, and metal fabricators rely on this stock for producing punches, dies, gauges, and other precision tooling components.

This flat stock is suited for small-shop and production toolroom environments where A2 tool steel is specified for moderate wear resistance and dimensional stability after heat treatment. The 36-inch length provides a practical working blank for cutting multiple parts or fabricating longer tooling components. The ground finish and tight tolerances reduce the amount of secondary grinding required before heat treatment.

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock blank for use in toolroom, die-making, and precision machining applications requiring AISI A2 material specification.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment. A2 tool steel must be heat treated by air hardening to achieve full hardness — follow established metallurgical procedures for austenitizing and controlled air cooling. Machining to final dimensions should be completed before heat treatment where possible. Handle ground surfaces carefully to avoid damage to the precision-ground finish.
