Measuring 3\/16 inch thick by 2 inches wide by 18 inches long, this flat stock is manufactured to tight dimensional tolerances, with thickness, width, and squareness all held to +0.010 to 0.015 inches and a length tolerance of +0.25 inches. AISI Type A2 tool steel offers good wear resistance and dimensional stability during heat treatment, making it a reliable choice for blanks, punches, and custom tooling components. Machinists and tool and die makers install and finish this material to print before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool rooms, and maintenance shops requiring a ready-to-machine A2 tool steel section. Common applications include die components, cutting blades, forming tools, gauges, and fixture components where moderate toughness and good wear resistance are needed. The 18-inch length provides a practical stock size for machining multiple smaller parts or a single longer component, and the 2-inch width covers a broad range of standard tooling cross-sections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type A2 air-hardening tool steel for dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003e3\/16 inch thickness x 2 inches wide x 18 inches long stock dimensions\u003c\/li\u003e\n\u003cli\u003eThickness, width, and squareness tolerance of +0.010 to 0.015 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.25 inches provides consistent oversize stock for facing to final length\u003c\/li\u003e\n\u003cli\u003eReady-to-machine condition suitable for tool room and die shop use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock section compatible with general tool room, die making, and precision machining applications requiring AISI A2 air-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate cutting tools rated for tool steel. Heat treatment, including hardening and tempering, should follow established metallurgical procedures for AISI A2 material and is typically performed by a qualified heat treating shop. Always secure workpieces properly before machining operations and use appropriate personal protective equipment. Consult material safety data sheets for guidance on handling tool steel swarf and cutting fluids.\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: 3\/16 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: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.91 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: 57165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542271263026,"sku":"57165","price":120.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_bab50d5b-af22-4b10-a14a-bb3ab000328a.jpg?v=1785896972","url":"https:\/\/voomisupply.com\/products\/starrett-57165-a2-tool-steel-flat-stock-3-16x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
