Starrett 54710 A2 Tool Steel Flat Stock 1x6x36 Inches

Product Description

The STARRETT 54710 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, and machine shops that need a precisely dimensioned raw material for tooling, jigs, fixtures, and dies. This bar measures 1 inch thick by 6 inches wide by 36 inches long and is held to tight tolerances throughout: thickness tolerance of plus or minus 0.001 inches, width tolerance of plus 0.000 to 0.005 inches, length tolerance of plus 0.25 inches, and squareness of 0.003 inches per inch on all edges. Weighing 70.37 pounds per bar, it ships as a single unit.

A2 air-hardening tool steel is a general-purpose cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is suited for blanking dies, forming dies, punches, gauges, and precision fixtures. It is appropriate for both short-run and production tooling applications in job shops, in-house tool rooms, and manufacturing maintenance departments. The air-hardening characteristic of A2 minimizes distortion during hardening compared to oil-hardening grades, making it a practical choice when close final dimensions must be maintained after heat treat.

Key Features

• Ready-to-machine flat stock format — 1 inch thick, 6 inches wide, 36 inches long

Compatibility

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

Installation Notes

This is raw flat stock material intended for machining, grinding, and heat treatment by qualified toolmakers or machinists. Follow established shop safety practices when cutting, grinding, or machining tool steel. Heat treatment — including hardening and tempering — should be performed by personnel familiar with A2 air-hardening procedures and appropriate furnace equipment. Always consult applicable material and safety data sheets before machining or heat treating.
