Measuring 5\/32 inches thick, 2 inches wide, and 18 inches long, this flat stock ships in an annealed condition ready for machining and subsequent air-hardening heat treatment. A2 tool steel offers good dimensional stability during hardening and a balanced combination of wear resistance and toughness, making it a reliable choice for punches, dies, gauges, and cutting tools. Weight is approximately 1.6 pounds per piece.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die shops, and maintenance departments that fabricate or repair tooling in-house. The 18-inch length provides enough material for a range of small-to-medium tool blanks. The flat bar geometry simplifies layout and reduces initial stock removal compared to round or square bar. Licensed machinists and toolmakers typically work this material on mills, surface grinders, and EDM equipment before hardening and tempering to final hardness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eDimensions: 5\/32 inches thick, 2 inches wide, 18 inches long\u003c\/li\u003e\n\u003cli\u003eThickness tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance: +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank suitable for use in toolmaking, die making, and precision fixture applications requiring air-hardening material per AISI A2 specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel working procedures. Follow the material manufacturer guidelines for annealing, hardening, and tempering temperatures specific to A2 tool steel. All grinding and cutting operations should be performed with appropriate coolant to prevent surface damage. Handle flat stock carefully to avoid nicks or bends that may cause stress concentrations in the finished tool.\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 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: 1.6 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: 57564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541398946098,"sku":"57564","price":126.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_66d500ca-06de-4b77-ae3f-a36360dae81b.jpg?v=1785874830","url":"https:\/\/voomisupply.com\/products\/starrett-57564-a2-tool-steel-flat-stock-5-32x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
