Manufactured from AISI A2 tool steel, this flat stock measures 3\/4 inches thick, 2 inches wide, and 18 inches long. Tolerances are held to +0.010 to 0.015 inches on thickness, width, and squareness, and +0.250 inches on length. The piece ships at approximately 7.65 pounds. A2 steel offers good dimensional stability during air-hardening heat treatment, making it a common choice where distortion control after hardening matters.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shop and tool room environments where technicians rough-machine the blank to near-net shape before hardening and finish-grinding to final dimensions. Typical applications include custom punch and die blanks, form tools, fixture components, and wear plates. The 18-inch length provides useful stock for multiple smaller blanks or a single longer component. It is sold as a single piece with a minimum order quantity of one.\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\u003eThickness: 3\/4 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 2 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with +0.250 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance held to +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eShips as a single pre-cut flat stock bar ready for machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank suitable for use in job shop, tool room, and die shop applications requiring AISI A2 air-hardening material in a 3\/4 x 2 x 18 inch form factor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with AISI A2 specifications. Follow applicable shop safety practices when cutting, grinding, or hardening this material. Heat treatment, including austenitizing and air-quench hardening, should reference the material manufacturer's published data sheet for proper temperature ranges and soak times. Proper personal protective equipment is required during all machining and heat treatment operations.\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\/4 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\u003eLength Tolerance\u003c\/strong\u003e: +0.250 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\u003eWeight\u003c\/strong\u003e: 7.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543921099058,"sku":"57216","price":468.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_a2264966-94c9-44f3-a8c2-ed646dc64329.jpg?v=1785922387","url":"https:\/\/voomisupply.com\/products\/starrett-57216-a2-tool-steel-flat-stock-3-4x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
