Measuring 0.5 inches thick, 0.625 inches wide, and 36 inches long, this flat stock is held to tight tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. The AISI A2 designation means this steel air-hardens with minimal distortion, making it a reliable choice for punches, dies, gauges, and similar tooling components. The piece ships at 3.66 pounds.\u003c\/p\u003e\u003cp\u003eA2 tool steel flat stock is primarily used by tool and die makers, machinists, and maintenance technicians in industrial and manufacturing environments. The 36-inch length allows for sectioning into multiple smaller blanks, and the pre-ground flat surfaces reduce setup time when machining to final dimensions. Typical applications include blanks for cutting tools, die components, fixture stock, and precision gauging elements where controlled heat treatment and dimensional consistency are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel with minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise dimensional control\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch length with plus 0.25-inch length tolerance for flexible sectioning\u003c\/li\u003e\n\u003cli\u003eShips as a single bar; no minimum order quantity beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications requiring controlled dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate equipment for hard-to-machine alloys. Always wear appropriate personal protective equipment when cutting, grinding, or heat-treating tool steel. Heat treatment of A2 steel requires controlled atmosphere or proper precautions to prevent decarburization; follow the material supplier specifications for hardening and tempering cycles. Allow the stock to fully cool before taking final measurements.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 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\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: 3.66 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: 57347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541671248178,"sku":"57347","price":314.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_5f43d568-3687-46ee-b441-dd4b577d33f1.jpg?v=1785881788","url":"https:\/\/voomisupply.com\/products\/starrett-57347-a2-tool-steel-flat-stock-0-5x0-625x36in","provider":"Voomi Supply","version":"1.0","type":"link"}
