Starrett 54669 A2 Tool Steel Flat Stock 0.5x5x36 in

Product Description

The STARRETT 54669 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Cut to 0.5 inches thick, 5 inches wide, and 36 inches long, this bar ships in an annealed condition ready for machining before hardening. A2 tool steel offers good dimensional stability during heat treatment and a favorable balance of wear resistance and toughness, making it a common choice for punches, dies, gauges, and forming tools. Tolerances are held to plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. The piece weighs approximately 29.32 pounds.

This flat stock is suited for tool and die shops, mold makers, and precision machine shops working with air-hardening grades. Typical uses include blanking dies, forming tools, cutting blades, and precision jigs where stable heat treat response is required. At 5 inches wide and 36 inches long, the bar provides enough material for multiple tooling components from a single piece. A licensed machinist or toolmaker typically machines this stock to final shape before sending it through the hardening cycle.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed in the annealed condition before heat treatment. Hardening, tempering, and stress relieving should be carried out by a qualified heat treater following accepted practices for AISI A2 tool steel. Appropriate personal protective equipment and machine guarding are required when cutting or grinding tool steel. Always verify final dimensions after heat treatment, as minor movement may occur.
