Measuring 5\/16 inch thick, 6 inches wide, and 18 inches long, this bar is manufactured to AISI A2 tool steel specification and held to a thickness tolerance of plus or minus 0.001 inches, a width tolerance of plus 0.000 to 0.005 inches, and a length tolerance of plus 0.250 inches. A2 tool steel offers good wear resistance and dimensional stability through the air-hardening heat treatment process, making it a reliable choice for punches, dies, gauges, and precision tooling components.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance departments where custom tooling blanks are machined, ground, or EDM-processed to final form. The 6-inch width and 18-inch length provide adequate blank size for a wide range of die plate, fixture plate, and tooling applications in both light manufacturing and production environments. The bar ships in single-piece quantity and is appropriate wherever tight squareness and flatness are required before secondary machining operations begin.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for predictable dimensional stability during heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise fitment in ground stock applications\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches and squareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.250 inches allows for facing and squaring to final dimension\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity with no minimum order above one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ground flat stock blank suitable for use in tool and die fabrication, fixture building, and precision machining applications that call for AISI A2 air-hardening tool steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and grinding of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting tools rated for hardened or pre-hardened steel. Heat treatment, including hardening and tempering of A2 tool steel, should follow established metallurgical procedures and should only be carried out by personnel with proper furnace equipment and quench controls. Always allow the workpiece to reach ambient temperature before taking final measurements. Secure workpieces properly during sawing or milling operations to prevent movement and dimensional inaccuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\/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: 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 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: 9.48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 54727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541256765746,"sku":"54727","price":559.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_ade55c4f-1e15-4b00-b352-b2bab3fc8610.jpg?v=1785870929","url":"https:\/\/voomisupply.com\/products\/starrett-54727-a2-tool-steel-flat-stock-5-16-x-6-x-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
