The piece measures 5\/32 inches thick, 2-1\/2 inches wide, and 18 inches long, with a weight of 2.01 pounds. A2 tool steel offers good toughness and wear resistance with minimal distortion during air-hardening heat treatment, making it a practical choice for punches, dies, gauges, and general tooling applications. This stock arrives in the annealed condition, ready for machining before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for use in tool and die shops, maintenance machine shops, and precision fabrication environments. It is a standard choice when fabricating or repairing tooling components that require subsequent hardening and finishing. The 18-inch length provides enough material for multiple smaller blanks depending on the layout. Thickness, width, and squareness tolerances are held tight, which reduces setup and dressing time at the machine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel (AISI A2) for predictable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness: 5\/32 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 2-1\/2 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with a tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to +0.010 to 0.015 inches for consistent material geometry\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank for use in tooling, die making, and precision machining applications requiring air-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling. Always follow applicable shop safety practices and equipment manufacturer guidelines when cutting, grinding, or heat-treating this material. Secure the stock firmly in a vise or fixture before machining to prevent movement. Do not attempt to harden this material without proper heat-treating equipment and temperature control.\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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-1\/2 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: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57565\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540336247090,"sku":"57565","price":196.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_9672502d-6505-4a42-9f19-ac90957ff2b0.jpg?v=1785852516","url":"https:\/\/voomisupply.com\/products\/starrett-57565-a2-tool-steel-flat-stock-5-32x2-1-2x18in","provider":"Voomi Supply","version":"1.0","type":"link"}
