Starrett 57616 A2 Tool Steel Flat Stock 9/16x2.5x18 in

Product Description

The STARRETT 57616 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.5625 inches thick, 2.5 inches wide, and 18 inches long, this flat stock is manufactured to close dimensional tolerances that support accurate stock removal and heat treatment. AISI Type A2 tool steel offers good wear resistance and dimensional stability during air-hardening, making it well suited for cutting tools, punches, dies, and gauges. The piece weighs approximately 7.17 pounds. Machinists and tool-and-die makers rely on pre-sized flat stock like this to reduce setup time and material waste when fabricating precision components.

This flat stock is appropriate for job shops, toolrooms, and production environments where A2 tool steel is specified. Typical applications include fabrication of blanking dies, form dies, trimming tools, and precision fixtures. The air-hardening characteristic of A2 steel means less distortion during heat treatment compared to oil-hardening grades, which is a practical advantage in tight-tolerance tooling work. It is sold in single-piece quantities.

Key Features

Compatibility

Designed as a standard A2 tool steel flat stock blank suitable for toolmaking, die making, and precision machining applications where AISI A2 air-hardening tool steel is specified.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers using appropriate equipment and personal protective equipment. Follow the material manufacturer's recommended hardening and tempering procedures for AISI A2 tool steel. Secure workpieces properly before any machining operations to prevent movement and ensure dimensional accuracy.
