Starrett 57327 A2 Tool Steel Flat Stock 5/32x1-3/4x36 in

Product Description

The STARRETT 57327 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.15625 inches thick, 1.75 inches wide, and 36 inches long, this flat stock is produced to tight dimensional tolerances, making it suitable for applications where accuracy and consistency are required before and after heat treatment. A2 tool steel is known for its good balance of wear resistance, toughness, and dimensional stability during air hardening. This material is typically sourced by tool and die makers, machinists, and maintenance shops needing a reliable, weldable, machinable tool steel in flat bar form.

This flat stock is suited for fabricating punches, dies, fixtures, gauges, and cutting tools in both job shop and production environments. It ships in the annealed condition and can be machined prior to heat treating. The 36-inch bar length makes it practical for multiple blanks from a single piece, reducing material waste in typical shop operations.

Key Features

• A2 air-hardening tool steel for excellent dimensional stability during heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for precision blank work
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus 0.25 inches
• Squareness held to 0.003 inches per inch on all edges
• Square tolerance of plus or minus 0.001 inches

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for general toolmaking, die making, and precision fixture fabrication where AISI A2 material specification is required.

Installation Notes

Machining and grinding operations should be performed in the annealed condition prior to heat treatment. Heat treating A2 tool steel should be carried out by a qualified heat treater following established procedures for air-hardening steels. Appropriate personal protective equipment and machine guarding are required when cutting or grinding tool steel bar stock. Always verify final dimensions after heat treatment, as some movement may occur.
