Measuring 1\/16 inch thick by 4 inches wide by 18 inches long, this flat stock ships in the annealed condition, ready for machining, grinding, and then air-quench hardening. AISI A2 offers good dimensional stability during hardening and a useful balance of wear resistance and toughness, making it a common choice for dies, punches, forming tools, and gauges. Weight is 1.29 pounds per piece.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is used in tool and die shops, maintenance departments, and precision machine shops for fabricating blanks that will be hardened in-house. The 4-inch width and 18-inch length give a practical starting size for medium-format punches, stripper plates, and fixtures. Because the stock hardens in still air rather than oil or water, distortion is minimized, which is especially valuable in wide, thin cross-sections like this 1\/16-inch thickness. Licensed machinists and toolmakers are the primary installers and processors of this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eAnnealed flat stock ready for machining and grinding prior to hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent fit in close-tolerance tooling\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to minus 0.005 inches\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\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement blank for applications requiring AISI A2 air-hardening tool steel flat stock in a 1\/16 x 4 x 18-inch profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eProcessing A2 tool steel flat stock should be performed by a qualified machinist or toolmaker familiar with tool steel heat treatment procedures. Follow the material manufacturer's recommended annealing, hardening, and tempering cycles for AISI A2; air-quench procedures require controlled shop conditions to achieve target hardness. Use appropriate grinding wheel grades and coolant when finish-grinding hardened sections to avoid surface burns. Consult applicable shop safety standards when handling and storing tool steel stock.\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: 1\/16 inches (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 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: 1.29 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: 85997781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52124422897970,"sku":"85997781","price":117.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_00cb22b8-a57d-4a96-90c4-a945b2dbf012.jpg?v=1790086804","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-85997781-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
