Measuring 0.5 inches thick by 1.25 inches wide by 36 inches long, this flat stock is held to tight dimensional tolerances, including plus or minus 0.001 inches on thickness and plus or minus 0.003 inches on squareness. A2 tool steel is an air-hardening, medium-alloy cold-work steel known for its excellent dimensional stability during heat treatment, good wear resistance, and moderate toughness. It is widely used by tool and die shops, machinists, and fabricators who need a reliable cold-work steel with predictable hardening behavior.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabrication of dies, punches, forming tools, gauges, and cutting tools in both job shop and production environments. The 36-inch length provides a practical starting blank for saw-cutting to finished part lengths. The A2 air-hardening designation means this material does not require quenching in oil or water, which reduces warpage risk during the hardening process. Machinists and tool makers working in general metalworking or precision tooling applications will find this stock ready for layout and machining in the annealed condition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precise fitment and machining\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches for consistent stock sizing\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance held to plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e36-inch length provides flexible cut-to-size capability\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, 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 replacement or raw material blank for cold-work tooling, die, punch, and gauge applications requiring AISI A2 air-hardening material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed in the annealed condition using appropriate metalworking equipment. Heat treatment, including hardening and tempering, should be performed by a qualified heat treater following established procedures for AISI A2 tool steel. Always use proper personal protective equipment when cutting, grinding, or machining tool steel stock.
