Starrett 54595 A2 Tool Steel Air-hardening Flat Stock

Product Description

The STARRETT 54595 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. This flat stock measures 0.125 inches thick, 3.5 inches wide, and 18 inches long, with a weight of 2.22 pounds. A2 tool steel offers good toughness and wear resistance with minimal distortion during air hardening, making it a reliable choice for punches, dies, gauges, and other precision tooling components. The 54595 is supplied in the annealed condition, ready for machining before hardening.

This flat stock is suited for tool rooms, machine shops, and fabrication environments where close-tolerance steel bar is required for custom tooling or replacement parts. Typical applications include blanking dies, forming tools, cutting blades, and fixture components. The controlled tolerances on all dimensions allow machinists to work directly from stock with predictable material removal. This material is appropriate for both production tooling and one-off prototype work where dimensional accuracy matters.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus 0.250 inches
• Square tolerance of plus or minus 0.001 inches
• Supplied in annealed condition, ready for machining

Compatibility

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

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Air hardening must be performed in a controlled atmosphere or vacuum furnace to prevent decarburization of the surface. Follow the steel manufacturer's recommended hardening and tempering temperature ranges for A2 material. Always allow the part to reach room temperature before final inspection of dimensions.
