A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment, moderate toughness, and good wear resistance. This flat stock is supplied in the annealed condition, ready for machining, grinding, and subsequent heat treatment. Machinists, tool and die makers, and toolroom professionals use this material to fabricate punches, dies, gauges, and other precision tooling components where consistent tolerance control is critical.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for cold-work tooling applications in job shops, tool rooms, and production environments. The 6-inch width and 18-inch length make it practical for medium-sized die sections, blanking punches, forming tools, and fixture components. Thickness tolerance is held to +0.010 to 0.015 inches, width tolerance to +0.010 to 0.015 inches, and length tolerance to +0.25 inches, providing a reliable starting blank that minimizes excess stock removal during machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel composition for minimal distortion during hardening\u003c\/li\u003e\n\u003cli\u003eThickness: 0.625 inches with +0.010 to 0.015 inches tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 6 inches with +0.010 to 0.015 inches tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with +0.25 inches tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to +0.010 to 0.015 inches for consistent perpendicularity\u003c\/li\u003e\n\u003cli\u003eSupplied annealed for ease of machining prior to heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank suitable for cold-work tooling, die making, and precision machining applications where air-hardening steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel should be performed by qualified machinists or toolroom personnel using appropriate cutting fluids and HSS or carbide tooling.
