Measuring 5\/16 inch thick by 1\/2 inch wide by 36 inches long, this flat stock ships in the annealed condition ready for machining, grinding, or profiling before hardening. A2 tool steel offers a good balance of wear resistance and toughness, making it a reliable choice for punches, dies, gauges, and similar tooling components. Thickness tolerance is held to plus or minus 0.001 inches. Weight is 1.83 pounds per piece.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited to toolmakers, machinists, and maintenance professionals fabricating precision tooling components. A2 material is commonly used in applications requiring air hardening to minimize distortion during heat treat. Typical uses include cutting tools, forming dies, blanking punches, and wear strips in light to medium production tooling. The 36-inch length allows multiple parts to be blanked from a single bar, reducing material waste in short-run tooling projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel — minimizes distortion during hardening compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal during grinding\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\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows machining and profiling prior to heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat bar suitable for general toolmaking and die-making applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed by qualified toolmakers or machinists using appropriate metalworking equipment. Heat treatment to final hardness must be performed in a controlled atmosphere or vacuum furnace to prevent decarburization. Allow the bar to reach ambient temperature before taking final dimensional measurements. Follow applicable shop safety practices when grinding hardened tool steel.\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 Type 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\/2 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\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.83 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: 57340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544433852722,"sku":"57340","price":190.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_00422d8f-4521-43f8-b9f8-6591a18eff58.jpg?v=1785926489","url":"https:\/\/voomisupply.com\/products\/starrett-57340-a2-tool-steel-flat-stock-5-16x1-2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
