It measures 0.75 inches thick, 1 inch wide, and 18 inches long, with a weight of 3.84 pounds. The A2 designation indicates an air-hardening, medium-alloy cold-work tool steel that offers good dimensional stability during heat treat, moderate toughness, and wear resistance suited to production tooling. Machinists, tool and die makers, and industrial maintenance technicians work with this material when a balance of hardness, toughness, and minimal distortion on hardening is required.\u003c\/p\u003e\u003cp\u003eThis flat stock is intended for industrial and manufacturing environments where precision ground stock is required in the annealed state for subsequent machining and heat treatment. Typical applications include making blanking dies, forming tools, gauges, jigs, and fixtures. The close thickness and squareness tolerances make it well suited for applications that demand consistent stock removal and predictable finished dimensions after hardening. It is sold as a single piece per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches for flat, parallel faces\u003c\/li\u003e\n\u003cli\u003eReady-to-machine annealed condition typical of precision ground flat stock\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 tool and die, fixture, and precision machining applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment by qualified machinists or tool and die makers. Follow established shop safety procedures, including eye protection and secure workholding, when sawing or milling this material. Heat treatment of A2 tool steel should be performed according to the material specification and applicable shop procedures; consult the material data sheet for austenitizing and quench guidelines. Handle edges carefully as precision ground stock can have sharp burrs after cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\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 plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 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\u003eWeight\u003c\/strong\u003e: 3.84 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 56501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539491225906,"sku":"56501","price":302.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_19617b86-8e11-4c7b-b7f8-dc76ffa7792e.jpg?v=1785841588","url":"https:\/\/voomisupply.com\/products\/starrett-56501-a2-tool-steel-flat-stock-3-4x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
