The bar measures 3\/32 inch thick, 3\/4 inch wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inch and a width tolerance of plus 0.000 to 0.005 inch. Length tolerance is plus 0.25 inch. These tight tolerances reduce layout and grinding time before heat treatment. A2 tool steel responds well to air-hardening, making it a practical choice where dimensional stability during heat treat is a priority.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool-and-die operations, and maintenance departments that fabricate or repair tooling in-house. The 36-inch length allows a single bar to yield multiple blanks for small- to medium-run tooling components. The 3\/32-inch thickness is commonly used for thin punches, wear plates, and small forming tools. Typical users include tool and die makers, precision machinists, and industrial maintenance technicians working in both production and prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for dimensional stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for precise blank-to-print fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inch\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inch per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock blank suitable for machining, grinding, and heat-treating applications in tool-and-die and general precision machining contexts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers using appropriate personal protective equipment.
