Starrett 54609 A2 Tool Steel Flat Stock 5/32x6x18 in

Product Description

The STARRETT 54609 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, punches, and precision machining applications. Measuring 5/32 inch thick, 6 inches wide, and 18 inches long, this flat stock is ground to close tolerances and ships ready for layout, machining, or heat treatment. Thickness and squareness tolerances are held to plus or minus 0.001 inch. Width tolerance runs plus 0.000 to 0.005 inch, and length tolerance is plus 0.250 inch. A2 tool steel offers good toughness, dimensional stability during air hardening, and broad utility across tool and die shop environments.

This flat stock is suited for fabricating dies, punches, gauges, fixtures, and forming tools in tool and die shops, precision machine shops, and industrial maintenance operations. A2 grade material is a common choice when air hardening is required to minimize distortion and preserve dimensional accuracy through the heat treatment cycle. The 6-inch width and 18-inch length provide enough stock for most small to medium tool blank applications. This piece is sold individually.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with air-hardening steel procedures. Always follow the material supplier and shop safety guidelines when grinding, cutting, or heat treating tool steel. Appropriate personal protective equipment is required during all machining and heat treatment operations. Consult AISI A2 data sheets for hardening and tempering temperature ranges before processing.
