Starrett 54605 A2 Tool Steel Flat Stock 5/32x3x18 in

Product Description

The STARRETT 54605 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 5/32 inches thick, 3 inches wide, and 18 inches long, this flat stock is supplied to tight dimensional tolerances: plus or minus 0.001 inches on thickness and square, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. AISI A2 tool steel offers good dimensional stability during heat treatment and strong wear resistance after hardening. At 2.38 pounds, this piece is practical for bench-size tooling and fixture work.

This flat stock is suited for tool and die shops, mold makers, and machine shops fabricating punches, dies, gauges, and precision fixtures. The air-hardening characteristic of A2 steel reduces distortion during the hardening process compared to oil-hardening grades, making it a practical choice where close-tolerance finished dimensions are required after heat treat. It is appropriate for both prototype and production tooling applications in industrial and job-shop environments.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches for consistent stock sizing
• Square tolerance of plus or minus 0.001 inches supports accurate layout and machining
• Ready-to-machine flat stock format saves setup time in die and tooling work
• Single-piece packaging with no minimum order quantity beyond one piece

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock for use in toolmaking, die making, and precision machining applications requiring AISI A2 material specification.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed by qualified toolmakers or machinists familiar with tool steel handling. Heat treatment, including hardening and tempering, should follow established procedures for AISI A2 material and is typically performed by a qualified heat treater. Use appropriate personal protective equipment when cutting, grinding, or machining. Consult material safety data and applicable shop safety standards before processing.
