A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and its resistance to wear and deformation under load. This flat stock is suited for toolmakers, machinists, and die shops that need a reliable, machinable blank before heat treat. At 4.78 pounds per piece, it offers a solid, ready-to-machine section with tight tolerances held on thickness, width, and squareness.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is commonly used in the production of dies, punches, jigs, fixtures, and gauges in both job shop and production environments. Its air-hardening characteristic reduces distortion compared to oil- or water-hardening grades, making it a preferred choice for precision tooling applications. Machinists and tool and die makers typically rough machine this stock to near-net shape before sending it to heat treat, then finish grind to final dimension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel construction for dimensional stability during hardening\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision blanks\u003c\/li\u003e\n\u003cli\u003eWidth tolerance held to plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches across the section\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.250 to 0.500 inches\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat bar format eliminates initial stock removal from round bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock for use in toolmaking, die making, and precision machining applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treating of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel requirements. Always relieve residual stresses with a proper stress-relief cycle before finish machining. Heat treatment, including hardening and tempering, should follow the material supplier's recommended thermal cycles for A2 tool steel. Use appropriate personal protective equipment and follow shop safety protocols when cutting, grinding, or handling sharp-edged 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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 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 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.250 to 0.500 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\u003eWeight\u003c\/strong\u003e: 4.78 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: 03718392\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51972018405682,"sku":"03718392","price":208.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_014f9eb4-5378-4599-abab-a88918b6fb86.jpg?v=1789961140","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-03718392-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
