A2 tool steel offers excellent dimensional stability during heat treatment, making it a preferred choice for dies, punches, gauges, and precision tooling components. This flat stock ships in the annealed condition, ready for machining before hardening. It 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 piece weighs approximately 58.64 pounds. Machinists, tool and die makers, and toolroom personnel are the primary users of this material.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock in this size is suited for medium to large tooling applications where close dimensional control and minimal distortion after hardening are required. Typical applications include blanking dies, forming dies, trim dies, cutting tools, and precision fixture components. The 1-inch thickness provides substantial cross-section for applications requiring deep machining, pocketing, or through-hole work. This bar is appropriate for job shops, tool rooms, and production environments fabricating long-run tooling that demands consistent hardness and wear resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment\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\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock suitable for general tooling, die-making, and precision machining applications requiring air-hardening steel in a 1 inch by 5 inch cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMaterial should be machined in the annealed condition before heat treatment. Heat treating A2 tool steel to final hardness should be performed by a qualified heat treater following established metallurgical procedures for AISI A2. Always allow the bar to reach a stable temperature before precision machining operations. Secure the workpiece properly using appropriate fixturing to prevent movement during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Air-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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\u003eWeight\u003c\/strong\u003e: 58.64 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: 54709\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542096216370,"sku":"54709","price":2222.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_00e5703f-82f9-43a0-b5fa-b81e8aa3fdb3.jpg?v=1785891946","url":"https:\/\/voomisupply.com\/products\/starrett-54709-a2-tool-steel-flat-stock-1x5x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
