Measuring 0.625 inches thick, 1 inch wide, and 36 inches long, this flat stock is held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. AISI A2 tool steel offers excellent wear resistance and dimensional stability during heat treatment, making it a reliable choice for fabricating punches, dies, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool rooms, and die shops requiring accurately sized stock before rough machining and heat treat. The AISI A2 grade air-hardens in still air, reducing distortion compared to oil-hardening grades. It is commonly used in residential and commercial toolmaking environments where consistent cross-section geometry and predictable heat-treat response are required. Machinists and tool-and-die makers specify this material for applications demanding close tolerances and good edge retention after hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precise stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches supports accurate layout\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch length with plus 0.25-inch length tolerance provides full usable stock\u003c\/li\u003e\n\u003cli\u003eWeighs 7.33 pounds, suitable for single-piece toolmaking applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar for use in toolmaking, die making, and precision machining applications requiring pre-sized flat stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis material is typically cut, machined, and heat-treated by tool-and-die makers or machinists in a shop environment.
