Measuring 3\/16 inches thick, 6 inches wide, and 36 inches long, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. A2 tool steel offers good wear resistance and dimensional stability during air-hardening heat treatment, making it a reliable choice for punches, dies, gauges, and similar toolroom components. Machinists, tool and die makers, and industrial fabricators work with this material regularly.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for precision toolroom and production shop environments where consistent stock dimensions and predictable heat-treat response are required. The A2 grade is a standard air-hardening tool steel recognized for balanced hardness, toughness, and moderate machinability in the annealed state. It is commonly used when oil-hardening grades like O1 introduce too much distortion risk, or when applications demand tighter dimensional control after hardening. Stock arrives in the annealed condition, ready for machining prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for reduced distortion during heat treatment compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal and close-tolerance work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches with edge squareness of 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eWeighs 13.19 pounds per bar, suitable for substantial tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for general toolroom, die-making, and precision machining applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and cutting of tool steel flat stock should be performed by qualified machinists using appropriate tooling rated for hardened or semi-hard steel. Always follow established heat-treatment procedures for A2 tool steel, including proper soak temperatures and controlled air-cooling, as specified by your heat-treat facility or the applicable material standard. Use appropriate personal protective equipment when sawing, grinding, or milling tool steel. Inspect stock dimensions before beginning layout to confirm bar is within tolerance for your application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.19 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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54576\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540710654258,"sku":"54576","price":757.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_40cb17e9-0ddb-4608-8ade-7c6cf9d7aa81.jpg?v=1785862614","url":"https:\/\/voomisupply.com\/products\/starrett-54576-a2-tool-steel-flat-stock-3-16x6x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
