Manufactured to AISI Type O1 specification, this flat stock measures 7\/32 inches thick, 3\/4 inches wide, and 36 inches long. Thickness tolerance is held to +\/- 0.001 inches, making it suitable for close-tolerance work where dimensional consistency matters before and after hardening. At 1.67 pounds per bar, it is sized for bench-scale toolroom use. Machinists, tool and die makers, and metalworking shops work with this material to produce punches, dies, gauges, and custom tooling components that require a hardened, wear-resistant final condition.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is a standard toolroom material used in job shops, maintenance departments, and manufacturing facilities. It is ordered in its annealed, soft state, machined to near-final dimensions, then oil-quench hardened and tempered to achieve working hardness. The 36-inch bar length provides a practical single-piece blank for most bench tooling projects. This bar is suited for applications where moderate toughness combined with good wear resistance after hardening is the design requirement.\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 held to +\/- 0.001 inches for close-tolerance stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to -0.005 inches provides consistent fit in slotted or guided setups\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.015 inches ensures full usable length on each bar\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length suits single-piece tooling blanks without additional cutoff waste\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 stock suitable for general toolroom, die, and fixture fabrication applications where this material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is worked by machinists and tool and die makers using conventional milling, grinding, and sawing equipment. Material should be machined in the annealed condition prior to heat treatment. Oil quench hardening and tempering must be performed by qualified personnel following established metallurgical procedures for AISI O1 tool steel. Allow the workpiece to reach ambient temperature before final grinding to finished dimensions after heat treat.\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: 7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 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: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.67 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: 54354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540341555506,"sku":"54354","price":149.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_bb56cb11-95a2-4a9a-92af-af746838e7a8.jpg?v=1785852721","url":"https:\/\/voomisupply.com\/products\/starrett-54354-o1-tool-steel-flat-stock-7-32x3-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
