This bar measures 0.5 inches thick, 2.5 inches wide, and 36 inches long, weighing approximately 12.75 pounds. A2 tool steel is known for its excellent dimensional stability during air hardening, making it well suited for punches, dies, forming tools, and precision fixtures where minimal distortion after heat treatment is critical. Thickness tolerance is held to plus or minus 0.001 inches, and square tolerance is held to plus or minus 0.003 inches.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool-and-die shops, machine shops, and industrial manufacturing environments for fabricating cutting tools, blanking dies, trim dies, gauges, and similar precision components. The 36-inch bar length provides a practical starting cut for a wide range of tooling applications. It is appropriate for both prototype and production tooling work where controlled heat treating and machinability are required before final hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel per AISI specification for minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance: plus or minus 0.001 inches for precise fit in close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance: plus or minus 0.250 to 0.500 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e36-inch bar length suitable for a wide range of tooling blanks and die components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock suitable for tooling, die-making, and precision machining applications that call for A2 grade material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and carbide tooling. Heat treating should follow AISI A2 guidelines and is typically performed in a controlled atmosphere furnace to minimize scaling and decarburization. Always wear appropriate PPE when cutting or grinding tool steel.
