Manufactured to AISI Type O1 specification, this flat stock measures 3\/16 inch thick, 10 inches wide, and 36 inches long, with a weight of 19.12 pounds. Tight dimensional tolerances are held throughout: thickness tolerance of plus or minus 0.001 inches, length tolerance of plus 0.015 inches, and width tolerance of 0.000 to 0.015 inches. Edge squareness is held to 0.003 inches per inch. This material is supplied in the annealed condition and is intended for machinists, tool and die makers, and fabricators who require consistent, close-tolerance stock before heat treatment.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is commonly used in production of punches, dies, gauges, jigs, fixtures, and cutting tools. The 10-inch width and 36-inch length make this bar suitable for larger die sets, plate tooling, and blanking applications where full-width material is needed. It is well suited for both small-shop and production-floor environments where reliable pre-hardened stock dimensions and predictable oil-quench hardening response are required. Machinists and tool makers machine this stock to final form, then harden and temper to application requirements.\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\u003eTight thickness tolerance of plus or minus 0.001 inches for close-tolerance tooling work\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.015 inches and length tolerance of plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLarge 10 x 36 inch profile suitable for die plates, fixtures, and blanking tooling\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 tool steel flat stock for general toolmaking, die making, and precision fabrication applications requiring close-tolerance pre-hardened material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and cutting of tool steel flat stock should be performed by qualified machinists using appropriate tooling for hardened or semi-hardened steel. Heat treatment, including oil quenching and tempering, should be carried out by personnel familiar with AISI O1 tool steel procedures and relevant shop safety requirements. Appropriate personal protective equipment must be worn when cutting, grinding, or heat treating this material. Consult material data sheets for recommended hardening and tempering temperature ranges before processing.\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\/16 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\u003eWeight\u003c\/strong\u003e: 19.12 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\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to 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\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: 54352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544610177330,"sku":"54352","price":990.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_ebb4dc4f-e146-41e3-afb1-f3a22bae16ba.jpg?v=1785931383","url":"https:\/\/voomisupply.com\/products\/starrett-54352-o1-tool-steel-flat-stock-3-16x10x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
