Measuring 0.5 inches thick, 8 inches wide, and 36 inches long, this bar is ground to tight dimensional tolerances suitable for jigs, fixtures, punches, and die components. The AISI A2 designation indicates a medium-alloy, air-hardening tool steel that offers good dimensional stability during heat treatment and excellent wear resistance in the hardened state. At 46.91 pounds, this is a full-length production bar intended for professional shop use. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers and users of this material.\u003c\/p\u003e\u003cp\u003eA2 tool steel flat stock in this size range is typically used in fabricating punch and die sets, blanking tools, forming tools, shear blades, and precision gauging fixtures. The 8-inch width and 36-inch length make this bar suitable for larger die plates or multiple smaller tooling blanks cut from a single piece. Its air-hardening characteristic reduces warpage compared to oil or water-hardening grades, making it a common choice when dimensional stability after heat treat is critical to the finished tool's function.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise as-ground stock\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 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches; edge squareness 0.003 per inch\u003c\/li\u003e\n\u003cli\u003eFull 36-inch length supports production blanking of multiple tooling pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 tool steel flat stock suitable for use in tool and die fabrication, fixture building, and precision machining where air-hardening steel in this thickness and width is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Always wear appropriate PPE including eye protection and gloves when cutting or grinding. Heat treatment of A2 tool steel should follow established metallurgical procedures for the AISI A2 grade; consult the material specification or a qualified heat treater before hardening. Ensure all cutting and grinding tools are rated for the hardness and abrasion resistance of tool steel.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 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 plus 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 46.91 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: 54672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542951854386,"sku":"54672","price":1334.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_3f9308ad-56cc-4a5c-a389-657d4433091b.jpg?v=1785911981","url":"https:\/\/voomisupply.com\/products\/starrett-54672-a2-tool-steel-flat-stock-0-5x8x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
