Starrett 54646 A2 Tool Steel Flat Stock 3/8x2x36 in

Product Description

The STARRETT 54646 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.375 inches thick, 2 inches wide, and 36 inches long, it is ground to tight tolerances on all faces, making it suitable for direct use as die blanks, punches, fixtures, and gauging components. The A2 tool steel grade offers good wear resistance, moderate toughness, and minimal distortion during air-hardening heat treatment. At 8.79 pounds per piece, it is a substantial bar suited for shop floor stock and custom fabrication. Machinists, tool and die makers, and toolroom technicians are the primary users of this material.

This flat stock is appropriate for both job shop and production toolroom environments where precise, ready-to-machine stock is required. It is well-suited for fabricating blanking dies, forming dies, cutting tools, gauges, and wear plates in light manufacturing and industrial maintenance settings. The pre-ground finish reduces setup time by minimizing stock removal before layout and machining operations begin. It is intended for use in the annealed condition and must be heat treated by a qualified technician or heat treat facility before use in hardened tooling applications.

• Pre-ground flat stock reduces setup and stock removal time

Compatibility

Designed as a standard A2 tool steel flat stock bar for general toolroom and die-making applications requiring air-hardening grade material to AISI A2 specification.

Installation Notes

This material is supplied in the annealed condition and requires heat treatment before use in hardened tooling applications. Heat treating A2 tool steel should be performed by a qualified professional following the material manufacturer guidelines for hardening and tempering temperatures. Use appropriate metalworking equipment and personal protective equipment when cutting, grinding, or machining. Secure the workpiece properly before any machining operation to prevent movement and dimensional error.
