Measuring 0.75 inches thick, 0.75 inches wide, and 18 inches long, this flat stock is supplied in the annealed condition and is designed to be machined to final shape before air-hardening heat treatment. AISI A2 tool steel offers good dimensional stability during hardening, moderate toughness, and wear resistance suited to a wide range of tooling applications. The bar weighs approximately 2.87 pounds.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool rooms, die shops, and maintenance departments in both industrial and commercial settings. Typical applications include fabricating blanking dies, form tools, gauges, and cutting blades where close dimensional control of the stock material reduces machining allowance. Tradespeople and machinists working in precision fabrication, mold making, and general tooling specify A2 flat stock for its predictable heat-treat response and consistent pre-machined dimensions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel construction for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003e0.75 inches thick by 0.75 inches wide cross-section, ready for layout and machining\u003c\/li\u003e\n\u003cli\u003e18-inch length provides sufficient blank material for most tooling applications\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +0.010 to +0.015 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of +0.010 to +0.015 inches maintains square cross-section accuracy\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.25 inches allows for facing and squaring to final length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock blank suitable for use wherever A2 grade tooling material is specified in tool room and die shop applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of A2 tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting speeds and tooling for tool steel. Material should be stress-relieved or annealed as required before finish machining. Heat treatment, including hardening and tempering, must follow established thermal processing procedures for AISI A2 and should be performed by personnel familiar with tool steel heat treatment practices. Handle bar stock carefully to avoid surface damage that could affect finished tool dimensions.\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.75 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: 2.87 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: 57213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540070334770,"sku":"57213","price":180.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_fab99a53-83a2-40c6-ba9a-726d3d768e28.jpg?v=1785846049","url":"https:\/\/voomisupply.com\/products\/starrett-57213-a2-tool-steel-flat-stock-0-75x0-75x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
