O1 is a general-purpose tool steel known for consistent hardening response, good machinability in the annealed state, and excellent edge retention after heat treatment. This flat stock is supplied in annealed condition and is ready for machining, grinding, and subsequent oil-quench hardening. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for precision tooling, jigs, fixtures, dies, and gauges where tight dimensional control is required before hardening. At 51 pounds, this is a full-size bar intended for shop or industrial use by tool and die makers, machinists, and moldmakers.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is used in tool rooms, die shops, and production machine shops. Common applications include blanking dies, forming dies, punches, drill jigs, fixture plates, and gauging components. The 10-inch width and 36-inch length provide ample stock for cutting multiple blanks from a single piece. This material is also appropriate for custom knife blanks and precision hand tools where a tough, hardenable steel is specified. Installation or use is carried out by machinists and tool and die makers in metal fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable, controlled heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for tight pre-machining dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, zero minus for consistent cut-to-length stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.015 inches negative for reliable fit in fixtures\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition for ease of machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general tool room and die shop applications requiring a hardenable, precision-tolerance steel flat stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding should be completed while the material is in the annealed state before oil-quench hardening. Heat treatment should follow established AISI O1 austenitizing and quenching procedures performed by qualified personnel using appropriate equipment. Secure workholding is required during machining given the part size and weight. Post-hardening grinding to final dimensions is standard practice for critical tolerance surfaces.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 10 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 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches, minus 0\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: 51 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: 54453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543394091314,"sku":"54453","price":1805.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_34d26e32-6c41-4136-8997-fd74609bf290.jpg?v=1785917801","url":"https:\/\/voomisupply.com\/products\/starrett-54453-o1-tool-steel-flat-stock-0-5x10x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
