A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good balance of wear resistance and toughness. This flat stock is supplied to tight tolerances, making it suitable for machining into dies, punches, gauges, and other precision tooling components. Machinists, tool and die makers, and industrial fabricators work with this material in job shops, maintenance departments, and prototype tooling environments.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is a standard choice for cold-work tooling applications where distortion during hardening must be minimized. The 0.625 inch by 3 inch by 18 inch bar provides enough material for a range of die and punch blanks, wear plates, and forming tools. Its air-hardening characteristic means the part can be hardened without quenching in oil or water, reducing the risk of cracking or warping in complex shapes. This bar ships as a single piece at the listed dimensions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to minus 0.005 inches for close-fit applications\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eAISI type A2 material specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat bar suitable for cold-work die and tooling fabrication applications where AISI A2 material is specified.\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 tool and die makers using appropriate metalworking equipment. Follow the steel manufacturer's published heat treatment guidelines for A2 tool steel, including proper preheat, austenitizing temperature, and air-cool procedures. Personal protective equipment including eye protection and gloves is required when cutting or grinding. Always verify final dimensions after any heat treatment cycle, as minor movement is possible even with air-hardening grades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches, Ends 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.67 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85998458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51972138336562,"sku":"85998458","price":244.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_27c44894-540b-48f8-b7ce-0f353b3f624c.jpg?v=1789963287","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-85998458-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
