Manufactured to AISI Type O1 material specification, this flat stock measures 1\/16 inch thick, 6 inches wide, and 36 inches long. It holds a thickness tolerance of plus or minus 0.001 inches and a length tolerance of plus 0.015 inches, making it suitable for applications requiring tight dimensional control before heat treat. Machinists, tool and die makers, and industrial fabricators stock this material for blanks, wear plates, and custom tooling components.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in job shops, maintenance departments, and toolrooms where O1 tool steel is the specified material. O1 is a widely used oil-hardening grade that machines well in the annealed state and responds predictably to heat treatment, making it a standard choice for punches, dies, gauges, and similar tooling. The 6-inch width and 36-inch length provide ample stock for cutting multiple blanks from a single bar. This item ships 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 Type O1 oil-hardening tool steel for predictable heat treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise pre-machined fits\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of minus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and precision fabrication applications where O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment by qualified machinists or toolmakers. Always follow safe handling practices when working with tool steel bar stock, including the use of proper personal protective equipment. Heat treatment of O1 steel requires controlled atmosphere or salt bath equipment and should be performed by personnel familiar with oil-quenching procedures. Sharp edges may be present on cut stock — deburr before handling or fitting.\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 Type O1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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: minus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge: All 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541978284338,"sku":"54269","price":369.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_0e8fc457-6869-4811-b981-bc4024a6fbba.jpg?v=1785888717","url":"https:\/\/voomisupply.com\/products\/starrett-54269-o1-tool-steel-flat-stock-1-16x6x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
