It measures 5\/32 inches thick, 3\/4 inches wide, and 36 inches long, with a weight of 1.37 pounds. A2 tool steel offers excellent dimensional stability during heat treatment, moderate wear resistance, and good toughness — characteristics that make it a common choice for dies, punches, and precision tooling components. This bar ships in a single piece and is intended for machining, grinding, or heat-treating to final application dimensions. Toolmakers, machinists, and die makers are the primary users.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for small tooling and fixture applications where close tolerances are required before and after heat treat. The 36-inch length allows for multiple part blanks to be cut from a single bar, reducing material waste in low-volume or prototype work. Thickness tolerance of plus or minus 0.001 inches and width tolerance of plus 0.000 to 0.005 inches make this bar suitable for applications where near-net stock dimensions reduce finish grinding time. It is appropriate for both manual and CNC machining operations prior to hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel — AISI Type A2 material specification\u003c\/li\u003e\n\u003cli\u003eThickness: 5\/32 inches with tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 3\/4 inches with tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength: 36 inches with tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: plus or minus 0.001 inches; edge squareness 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWeight: 1.37 pounds per bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard toolroom flat stock bar for use in tool and die, punch, fixture, and general precision machining applications requiring A2 air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of A2 tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting tools rated for tool steel. Heat treatment — including hardening and tempering — should follow the material manufacturer's guidelines for AISI A2 and must be performed in a controlled atmosphere or vacuum furnace to minimize decarburization. Handle bar stock with care to avoid surface nicks or burrs that can affect tolerance-critical applications. Always use proper workholding and cutting fluid when milling or grinding to final dimensions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.37 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: 57326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539450495282,"sku":"57326","price":157.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_79e3617a-b0c5-4c70-a6ae-917ea23d69e4.jpg?v=1785840549","url":"https:\/\/voomisupply.com\/products\/starrett-57326-a2-tool-steel-flat-stock-5-32x3-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
