Starrett 56514 A2 Tool Steel Flat Stock 0.875x1x36 in

Product Description

The STARRETT 56514 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. It measures 0.875 inches thick, 1 inch wide, and 36 inches long, with a weight of 10.26 pounds. Manufactured from AISI Type A2 tool steel, this flat stock offers tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. Machinists, tool-and-die makers, and metalworking professionals use this material as raw stock for punches, dies, gauges, and cutting tools prior to heat treatment.

This flat stock is suited for applications requiring close tolerance, pre-hardened or anneal-state bar stock in toolroom and production environments. A2 tool steel responds well to air-hardening heat treatment, making it a practical choice for fabricating dies, blanking punches, forming tools, and similar precision components. It is appropriate for both one-off toolroom jobs and short-run production where dimensional consistency matters from the raw stock stage.

Key Features

• AISI Type A2 air-hardening tool steel for predictable, low-distortion hardening
• Thickness tolerance of plus or minus 0.001 inches for close-tolerance toolroom work
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus 0.25 inches
• Square tolerance of plus or minus 0.001 inches with edge squareness of 0.003 inches per inch
• Ready-to-machine annealed condition flat bar, 36 inches long

Compatibility

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

Installation Notes

Machining and heat treatment of A2 tool steel flat stock should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Follow the material supplier and applicable shop safety guidelines when sawing, milling, or grinding. Air-hardening heat treatment requires controlled atmosphere or protective wrap to minimize decarburization and should be performed in properly rated heat-treat equipment. Always allow the bar to reach a stable temperature before machining to ensure dimensional accuracy.
