O1 tool steel is a general-purpose oil-hardening grade known for good machinability in the annealed state and for holding a sharp, stable edge after heat treatment. This flat stock is produced to tight dimensional tolerances, making it a reliable starting material for toolmakers, die makers, and machine shops fabricating punches, dies, gauges, jigs, and cutting tools. At 81.6 pounds per bar, it is a heavy, full-size section suited for larger tool and die applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in industrial and tool room environments where close-tolerance raw material is required before heat treating and finish grinding. Typical applications include blanking dies, forming dies, short-run punches, and precision fixtures. The 36-inch length provides standard stock for saw-cutting multiple blanks. It is appropriate for both job shop and in-house tool room use wherever O1 oil-hardening tool steel is specified by print or process.\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 consistent stock removal allowance\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, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge all 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eFull 36-inch length supports multiple blank cuts from a single bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock for general tool and die fabrication requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate metal-cutting equipment. Wear proper PPE including eye protection and cut-resistant gloves when handling and sawing heavy steel bar stock. O1 tool steel must be hardened and tempered per established heat treat procedures before use in cutting or forming applications. Do not attempt to weld O1 tool steel without following qualified pre-heat and post-heat procedures appropriate to the application.\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\u003eOverall Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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, minus 0 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: 81.6 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: 54541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542517678386,"sku":"54541","price":2149.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_900b8a68-f60a-45f7-bc74-33afca30835a.jpg?v=1785902629","url":"https:\/\/voomisupply.com\/products\/starrett-54541-o1-tool-steel-flat-stock-2x4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
