Starrett 57574 A2 Tool Steel Flat Stock 3/16x1-3/4x18 in

Product Description

The STARRETT 57574 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, fixture fabrication, and precision machining applications. Measuring 3/16 inches thick by 1-3/4 inches wide by 18 inches long, this flat stock is cut and ground to close dimensional tolerances suitable for direct use in tool and die shops. A2 tool steel offers good toughness combined with air-hardening characteristics, making it a practical choice where dimensional stability through the heat-treat cycle is required. This piece weighs approximately 1.73 pounds and ships as a single unit.

This flat stock is intended for machinists, tool and die makers, and metalworking tradespeople who need a reliable A2 tool steel blank for custom tooling, punches, dies, gauges, or similar precision components. The 18-inch length provides workable stock for a range of small to medium tooling projects. The close thickness, width, and squareness tolerances reduce setup time when laying out or machining to final dimension.

Installation Notes

Cutting, grinding, and heat treating tool steel should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Always follow established shop safety practices when machining or grinding tool steel, including proper guarding and eye protection. Heat treatment of A2 steel should follow the material manufacturer's recommended hardening and tempering procedures. Consult applicable shop standards and material data sheets before processing.
