Starrett 57314 A2 Tool Steel Flat Stock 3/32x1-1/2x36 in

Product Description

The STARRETT 57314 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 3/32 inch thick, 1-1/2 inches wide, and 36 inches long, this flat stock is manufactured to tight dimensional tolerances, making it suitable for applications where consistent size and squareness are critical. The material conforms to AISI Type A2 specification, a cold-work tool steel known for its good dimensional stability during heat treatment. Machinists, tool-and-die makers, and metalworking professionals use this stock to fabricate punches, dies, gauges, and similar precision components. It ships at approximately 1.65 pounds.

This flat stock is suited for job shop and production toolroom environments where reliable stock dimensions reduce setup time and rework. AISI A2 tool steel air-hardens, meaning it requires less quenching severity than oil-hardening grades, which reduces distortion risk on finished workpieces. The 36-inch length provides sufficient material for a range of small-to-medium tooling projects. It is commonly used in both low-volume prototype work and higher-run die and fixture fabrication. Trade professionals working in precision metalworking, manufacturing maintenance, and industrial toolmaking will find this stock appropriate for demanding dimensional requirements.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate metalworking equipment. Follow established heat-treat procedures for AISI A2 tool steel when hardening and tempering finished components. Eye protection, proper workholding, and appropriate cutting fluids should be used during machining operations. Consult applicable shop safety standards and material data sheets before processing this material.
