Starrett 57347 A2 Tool Steel Flat Stock 0.5x0.625x36in

Product Description

The STARRETT 57347 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 0.5 inches thick, 0.625 inches wide, and 36 inches long, this flat stock is held to tight tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. The AISI A2 designation means this steel air-hardens with minimal distortion, making it a reliable choice for punches, dies, gauges, and similar tooling components. The piece ships at 3.66 pounds.

A2 tool steel flat stock is primarily used by tool and die makers, machinists, and maintenance technicians in industrial and manufacturing environments. The 36-inch length allows for sectioning into multiple smaller blanks, and the pre-ground flat surfaces reduce setup time when machining to final dimensions. Typical applications include blanks for cutting tools, die components, fixture stock, and precision gauging elements where controlled heat treatment and dimensional consistency are required.

Compatibility

Designed as a standard A2 air-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications requiring controlled dimensional tolerances.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate equipment for hard-to-machine alloys. Always wear appropriate personal protective equipment when cutting, grinding, or heat-treating tool steel. Heat treatment of A2 steel requires controlled atmosphere or proper precautions to prevent decarburization; follow the material supplier specifications for hardening and tempering cycles. Allow the stock to fully cool before taking final measurements.
