It measures 0.5 inches thick, 1.25 inches wide, and 36 inches long, and weighs approximately 7.33 pounds. AISI A2 tool steel offers excellent dimensional stability during air hardening, making it a preferred choice for punches, dies, gauges, and cutting tools where tight tolerances must be maintained through the hardening cycle. The bar ships in an annealed condition and is machined to close tolerances on all faces.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, toolrooms, and production die-making operations in both light industrial and heavy manufacturing environments. Typical applications include blanking dies, form punches, trim dies, and precision gauging components. The 36-inch length allows machinists to cut multiple blanks from a single bar. The combination of controlled width, thickness, and squareness tolerances reduces the amount of material removal required before layout and machining begin.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for excellent size stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches; edge squareness 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eShips annealed and ready for machining prior to heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank for use in toolroom, die-making, and precision machining applications requiring air-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for hardened or semi-hardened steels. Heat treatment, including austenitizing and air-hardening cycles, should follow AISI A2 guidelines and be performed by a qualified heat treater. Secure the bar properly in a vise or fixture before cutting to prevent movement. Allow the bar to reach ambient temperature before taking final measurements after any machining operation.\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 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: 1.25 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 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: 7.33 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: 57348\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543516053810,"sku":"57348","price":336.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_08277608-d42b-4472-a4f6-05b2b660397c.jpg?v=1785919826","url":"https:\/\/voomisupply.com\/products\/starrett-57348-a2-tool-steel-air-hardening-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
