Measuring 0.5 inches thick, 2 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.001 inches on squareness, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. A2 tool steel is known for its excellent dimensional stability during heat treatment, making it a preferred choice for dies, punches, gauges, and cutting tools where precision and wear resistance are required. This stock ships at approximately 5.09 pounds.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool and die shops, and industrial fabrication environments. It is typically used to fabricate blanks for punches, forming dies, trim dies, and precision fixtures. A2 air-hardening steel is commonly selected when a balance of toughness, wear resistance, and minimal distortion on hardening is needed. It is appropriate for both prototype tooling and production-grade tool fabrication where close tolerances must be maintained through the machining and heat treat process.\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 held to plus or minus 0.001 inches for consistent stock removal in machining\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches supports precise blank sizing\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches reduces setup time on surface grinders and mills\u003c\/li\u003e\n\u003cli\u003e18-inch length with a plus 0.250-inch length tolerance provides usable material for multiple blanks\u003c\/li\u003e\n\u003cli\u003eReady-to-machine condition suitable for annealed flat stock applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock blank compatible with conventional toolmaking, die-making, and precision machining workflows where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with air-hardening steels. Always follow appropriate shop safety practices when grinding, milling, or EDM-processing tool steel stock. Heat treatment, including hardening and tempering cycles, should be performed according to AISI A2 specifications using a controlled-atmosphere furnace to minimize scaling and decarburization. Secure workpieces properly before machining to maintain the close tolerances this stock is ground to.\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: 2 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: 5.09 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: 54748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544481333554,"sku":"54748","price":334.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_dfcb95ea-c97c-4e4a-8818-1daf34844175.jpg?v=1785927576","url":"https:\/\/voomisupply.com\/products\/starrett-54748-a2-tool-steel-flat-stock-0-5x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
