The bar measures 5\/16 inches thick, 1 inch wide, and 18 inches long, held to tight tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.001 inches on squareness, and a positive 0.000 to 0.005 inches on width. A2 tool steel offers excellent dimensional stability during heat treatment and good wear resistance, making it a reliable choice for punches, dies, gauges, and similar tooling applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance departments that need a known-alloy blank they can machine, grind, and then air-harden in-house. The 18-inch length provides enough material for multiple smaller tool blanks from a single piece. The 5\/16-inch by 1-inch cross section is a common size for forming dies, stripper plates, and precision guide components in both light industrial and heavy manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of positive 0.000 to 0.005 inches allows finish grinding to final size\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches supports accurate layout and fixturing\u003c\/li\u003e\n\u003cli\u003eLength tolerance of positive 0.250 inches provides usable overage for facing operations\u003c\/li\u003e\n\u003cli\u003e18-inch bar length yields multiple blanks from one piece\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 machining and heat-treating operations wherever AISI A2 air-hardening tool steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel flat stock is typically performed by qualified machinists or tool and die makers using appropriate cutting fluids and carbide or high-speed tooling. Air-hardening heat treatment should follow the material manufacturer's recommended austenitizing and quench procedure for AISI A2; this work is best performed by a qualified heat treater. Always use proper personal protective equipment when cutting, grinding, or handling tool steel stock. Deburr all edges before handling or storing finished blanks.\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: 5\/16 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: positive 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: positive 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: 1.64 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: 54717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544453939506,"sku":"54717","price":103.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_766b5a2a-1e1d-4cb7-862c-e4daea102662.jpg?v=1785926999","url":"https:\/\/voomisupply.com\/products\/starrett-54717-a2-tool-steel-flat-stock-5-16x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
