Measuring 0.75 inches thick, 3 inches wide, and 18 inches long, this flat stock ships in a ground and precision-toleranced condition. Thickness and squareness tolerances are held to plus or minus 0.001 inches, while width tolerance runs from plus 0.000 to plus 0.005 inches and length tolerance is plus 0.250 inches. A2 tool steel offers good dimensional stability during air-hardening heat treatment, making it a preferred choice for punches, dies, and gauges. Machinists and toolmakers install this material in the annealed state before heat treating to final hardness.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance departments that fabricate or repair cutting tools, forming dies, and wear components. The 0.75 by 3 by 18 inch size provides enough stock for medium-sized die sections or multiple smaller tool blanks. A2 material is appropriate for applications requiring moderate toughness combined with good wear resistance and low distortion after hardening. It is commonly used in both light production tooling and prototype fixture work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for low distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003ePrecision ground flat stock with thickness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches for consistent fitment in die sets\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches supports accurate layout and machining\u003c\/li\u003e\n\u003cli\u003e18-inch length provides flexible cut-off options for multiple blanks\u003c\/li\u003e\n\u003cli\u003eShips as a single piece ready for machining in the annealed condition\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 toolmaking, die making, and precision machining applications requiring air-hardening tool steel in ground flat bar form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding should be performed in the annealed state prior to heat treatment. Heat treating A2 tool steel to final hardness requires controlled atmosphere or vacuum furnace equipment and should be performed by a qualified heat treater following AISI A2 guidelines. Use appropriate personal protective equipment when cutting or grinding tool steel. Secure the workpiece properly before any machining operation to prevent movement and maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 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 plus 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: 11.44 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: 54773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543411491122,"sku":"54773","price":617.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_e1b2167f-f885-44df-8d24-739248137c18.jpg?v=1785918232","url":"https:\/\/voomisupply.com\/products\/starrett-54773-a2-tool-steel-flat-stock-3-4x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
