Measuring 3\/32 inches thick, 6 inches wide, and 36 inches long, this flat stock is produced from AISI Type O1 tool steel and supplied in the annealed condition, ready for machining and subsequent oil-hardening heat treatment. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional consistency is critical before and after heat treat. Machinists, tool and die makers, and skilled fabricators are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size is commonly used to produce punches, dies, gauges, cutting tools, and precision fixtures in job shops, toolrooms, and manufacturing facilities. The 6-inch width and 36-inch length provide sufficient stock for multiple smaller blanks or a single large die plate. The annealed condition allows for conventional machining prior to hardening and tempering to final hardness. This size is appropriate for both light and moderate tooling applications where oil-quench heat treatment is the specified process.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for excellent machinability in the annealed state\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for close-tolerance tooling work\u003c\/li\u003e\n\u003cli\u003eEdge squareness: all edges 0.003 inches per inch maximum deviation\u003c\/li\u003e\n\u003cli\u003eLength tolerance plus 0.015 inches, zero minus, allowing safe rough-cut allowance\u003c\/li\u003e\n\u003cli\u003eWidth tolerance zero to minus 0.005 inches for consistent fit in mating components\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with a minimum order quantity of one\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 toolroom and die-making use where O1 specification material is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of O1 tool steel flat stock should be performed by qualified machinists familiar with tool steel working practices. Use appropriate cutting speeds and feeds for annealed tool steel, and ensure adequate coolant is applied during cutting and grinding operations. Heat treatment, including hardening and tempering, should be carried out by personnel trained in tool steel heat treat procedures in accordance with applicable shop standards. Handle large flat stock with care to avoid edge damage that could affect squareness tolerances.\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\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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: 5.74 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: 54289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542485139762,"sku":"54289","price":445.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_4c3021f4-9e0a-425d-8493-51b1554a6bb2.jpg?v=1785901602","url":"https:\/\/voomisupply.com\/products\/starrett-54289-o1-tool-steel-flat-stock-3-32x6x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
