Measuring 0.625 inches thick, 1.5 inches wide, and 36 inches long, this flat stock is produced to 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. The length tolerance is plus 0.25 inches. Squareness is held to an edge tolerance of 0.003 inches per inch across all edges. Machinist and toolroom professionals use this material for punches, dies, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eA2 tool steel is a general-purpose air-hardening grade known for good wear resistance, moderate toughness, and dimensional stability during heat treat. This flat stock is suited for low-to-medium production tooling where through-hardening and minimal distortion are priorities. It is supplied in the annealed condition, ready for machining before heat treatment. Typical users include tool and die makers, mold shops, and maintenance machinists working in both job shop and industrial manufacturing 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 treat\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches on 36-inch bar\u003c\/li\u003e\n\u003cli\u003eSupplied annealed and ready for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock bar for use in toolmaking, die making, and precision machining applications requiring air-hardening material in annealed condition.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining, grinding, and heat treating of A2 tool steel should be performed by qualified toolroom machinists or heat treat professionals familiar with AISI A2 procedures. Always follow applicable shop safety standards when cutting or grinding tool steel.
