Manufactured to AISI Type O1 specification, this flat stock measures 5\/32 inches thick, 8 inches wide, and 18 inches long, with a weight of 6.39 pounds. The tight thickness tolerance of plus or minus 0.001 inches makes it suitable for applications where dimensional accuracy is critical before and after heat treatment. Machinists, toolmakers, and die makers rely on O1 flat stock for punches, dies, gauges, and cutting tools where oil-quench hardening is part of the process.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in job shops, tool and die operations, and maintenance machining environments. O1 tool steel is well suited for applications requiring good wear resistance and moderate toughness after hardening. The 8-inch width and 18-inch length provide sufficient material for a range of tooling blanks and fixture components. The squareness specification of 0.003 inches per inch on all edges supports accurate layout and machining without additional dressing in many cases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for controlled heat treatment and good wear resistance\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise pre-hardening stock dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.005 inches under nominal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness of 0.003 inches per inch on all sides\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock at 5\/32 inches thick, 8 inches wide, 18 inches long\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolmaking, die making, and precision machining applications where AISI Type O1 material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is worked by machinists and toolmakers using conventional milling, grinding, and EDM equipment. Heat treatment should follow established AISI O1 oil-quench procedures performed by qualified personnel with appropriate furnace and quench equipment. Grind or machine to final dimensions before hardening where tolerances allow. Follow applicable shop safety procedures when handling sharp-edged stock and hot workpieces during heat treatment.\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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.39 pounds\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 0.005 inches under nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 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\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: 54041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542694494514,"sku":"54041","price":423.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_ca2f8859-2502-4961-b6db-d6f12fb2f13e.jpg?v=1785904490","url":"https:\/\/voomisupply.com\/products\/starrett-54041-o1-tool-steel-flat-stock-5-32x8x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
