Starrett 57652 A2 Tool Steel Flat Stock 1x5x18 Inches

Product Description

The STARRETT 57652 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 1 inch thick, 5 inches wide, and 18 inches long, this flat stock is manufactured from AISI Type A2 tool steel, a versatile air-hardening grade known for its dimensional stability during heat treatment and good wear resistance. Thickness, width, and square tolerances are held to +0.010 to 0.015 inches, with a length tolerance of +0.25 inches. At 25.28 pounds, this is a substantial billet suited for shop use requiring consistent material quality and close dimensional control.

A2 air-hardening flat stock is commonly used by tool and die makers, machinists, and metalworking shops for fabricating punches, dies, gauges, forming tools, and jigs. The air-hardening characteristic of A2 steel minimizes warpage and distortion during the hardening process, making it well suited for components that require tight post-heat-treat tolerances. This flat stock is appropriate for both prototype and production tooling in industrial and job-shop environments.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate tooling and personal protective equipment. Heat treatment of A2 tool steel should follow established metallurgical procedures and is typically performed by a qualified heat treater. Always secure the workpiece properly before machining operations. Consult applicable shop safety standards before cutting or processing this material.
