A2 tool steel is a versatile, medium-alloy, air-hardening grade known for its dimensional stability during heat treatment and good wear resistance. This flat stock is supplied in the annealed condition, ready for machining before hardening. Thickness, width, and squareness tolerances are held to +0.010 to +0.015 inches, and length tolerance is +0.250 inch. Machinists, tool-and-die makers, and metalworking shops use this material to fabricate punches, dies, gauges, and other precision tooling components.\u003c\/p\u003e\n\u003cp\u003eA2 air-hardening flat stock is a standard choice for toolroom and job-shop applications where close-tolerance blanks are needed without the quench distortion risk of oil-hardening grades. The 18-inch length provides sufficient stock for a range of die and fixture components. At 9.56 pounds, this bar is sized for bench machining on a manual or CNC mill before final heat treatment and grinding to finished dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA2 air-hardening tool steel for minimal distortion during heat treat\u003c\/li\u003e\n  \u003cli\u003eThickness: 3\/4 inch with +0.010 to +0.015 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eWidth: 2-1\/2 inches with +0.010 to +0.015 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eLength: 18 inches with +0.250 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eSquareness tolerance held to +0.010 to +0.015 inches\u003c\/li\u003e\n  \u003cli\u003eSupplied in annealed condition for ease of machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI Type A2 air-hardening tool steel flat stock suitable for general toolroom fabrication of dies, punches, gauges, and fixture components where dimensional stability during hardening is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis material is worked by qualified machinists and tool-and-die makers using standard milling, drilling, and grinding equipment. Machine to near-final dimensions before sending to heat treatment, as A2 steel is air-hardened and should not be quenched in oil or water. Follow the material supplier heat-treat specifications for austenitizing temperature and temper cycles.
