Manufactured to AISI Type O1 specification, this flat stock measures 3\/8 inches thick, 1-3\/4 inches wide, and 36 inches long, with a weight of 6.69 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making this material suitable for applications where dimensional accuracy before hardening is critical. Machinists, tool and die makers, and industrial maintenance professionals use O1 flat stock as a starting material for punches, dies, gauges, and cutting tools that require oil-quench hardening to reach final hardness.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size is a common choice for low-to-medium production tooling in job shops, maintenance departments, and fabrication facilities. The 36-inch bar length allows for multiple pieces to be cut from a single bar, reducing waste on smaller tool blanks. This material is appropriate for applications where the finished part will undergo oil quenching and tempering to achieve desired hardness, and where good machinability in the annealed state is required prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for consistent heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precise pre-machining stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 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: all edges within 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSingle 36-inch bar per package, sold individually\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 toolmaking, die making, and precision machining applications requiring an oil-quench hardenable material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be performed while the material is in the annealed state before heat treatment. O1 tool steel is oil-quench hardened and should be processed by a qualified heat treater or machinist familiar with tool steel hardening procedures. Appropriate personal protective equipment and machine guarding are required when sawing or grinding flat stock. Follow applicable shop safety standards and equipment manufacturer guidelines when cutting 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\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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-3\/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: 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: All edges 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.69 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: 54412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544524783922,"sku":"54412","price":316.41,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_78e92b8e-972d-4a35-a722-5cc0486a4434.jpg?v=1785928769","url":"https:\/\/voomisupply.com\/products\/starrett-54412-o1-tool-steel-flat-stock-3-8x1-3-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
