Manufactured to AISI Type O1 material specification, this flat stock is a general-purpose tool steel known for its consistent hardening response in oil-quench heat treatment. Thickness and squareness tolerances are held to plus or minus 0.001 inches, making it suitable for toolmaking, die work, and precision machining applications where dimensional control before hardening is critical. Machinists, tool and die makers, and metalworking fabricators are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is used in shops producing punches, dies, cutting tools, gauges, and fixtures that require a hardenable steel with predictable oil-quench response. The 36-inch length provides a full bar suitable for multiple blanks. This stock is supplied in the annealed condition, ready for machining to net shape before heat treatment. It is appropriate for both short-run toolmaking and prototype work in manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — consistent response to oil-quench heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness and squareness held to plus or minus 0.001 inches for close-tolerance toolmaking\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches — stock is never over-width\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches — full usable length guaranteed\u003c\/li\u003e\n\u003cli\u003eEdge squareness: all edges within 0.003 inches per inch of run\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening flat stock for general toolmaking, die making, and precision machining applications requiring a hardenable tool steel in flat bar form.\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 tool and die makers. Work to final dimensions before heat treatment, as hardening will alter machinability. Follow established heat treatment procedures for AISI O1 steel, including proper soak temperature and oil-quench technique, per your shop or a qualified heat treater. Handle hardened stock carefully to avoid edge chipping.\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: 2-1\/2 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: Edge: all 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.56 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: 54414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542097690930,"sku":"54414","price":298.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_9b99bad0-1a1d-4174-bd8f-61150c001ddc.jpg?v=1785891969","url":"https:\/\/voomisupply.com\/products\/starrett-54414-o1-tool-steel-flat-stock-3-8x2-1-2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
