Measuring 1 inch thick by 1-1\/4 inches wide by 36 inches long, this flat stock is held to a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. The length tolerance is plus 0.25 inches. Edge squareness is held to 0.003 inches per inch across all edges. A2 tool steel offers good dimensional stability during air-hardening heat treatment, making it a common choice for punches, dies, and precision tooling components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabrication of cutting tools, forming dies, gauges, and other toolroom applications where close tolerances and post-machining heat treatment are required. It is appropriate for both job shop and production toolroom environments. The 36-inch bar length allows for multiple part blanks to be cut from a single piece, reducing material waste on medium-run tooling projects. Licensed machinists and tool and die makers are the primary trade working with this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for predictable heat treatment and minimal distortion\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance blanking\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length yields multiple blanks per piece\u003c\/li\u003e\n\u003cli\u003eAISI A2 material specification for consistent alloy composition\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 toolroom applications requiring air-hardening material in this thickness and width range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers following established shop safety procedures. Eye and hand protection are required during cutting and grinding operations. Heat treatment of A2 steel requires controlled atmosphere or salt bath equipment to achieve proper hardness; follow the material manufacturer's heat treatment guidelines for austenitizing temperature, quench method, and temper cycles. Allow material to reach ambient temperature before performing final grinding or lapping to finished 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\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.66 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: 57352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540543930674,"sku":"57352","price":780.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_e49ab898-8bf4-4794-8abc-b1400863c596.jpg?v=1785858060","url":"https:\/\/voomisupply.com\/products\/starrett-57352-a2-tool-steel-flat-stock-1x1-25x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
