Manufactured from AISI Type O1 tool steel, this flat stock measures 5\/32 inches thick, 3 inches wide, and 18 inches long. It holds a thickness tolerance of +\/- 0.001 inches and a width tolerance of 0.000 to 0.005 inches, making it suitable for applications where dimensional accuracy before hardening is critical. Machinists and tool-and-die makers select O1 stock for its consistent pre-heat properties and predictable response to oil-quench hardening. The piece weighs approximately 2.39 pounds.\u003c\/p\u003e\u003cp\u003eO1 oil-hardening flat stock is commonly used in tool and die shops, machine shops, and maintenance departments. Typical applications include punch blanks, die components, cutting tools, gauges, and fixtures where the stock will be machined to shape and then hardened. This bar is supplied in the annealed condition, ready for machining prior to heat treatment. Its 18-inch length accommodates most bench-scale tooling projects without requiring further cutting in many cases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel construction for consistent hardenability\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +\/- 0.001 inches for precise pre-machining fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.250 inches, 0.000 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent oil-quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolmaking, die making, and precision fixture fabrication in machine shop and maintenance environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel stock should be performed by qualified machinists or toolmakers familiar with AISI O1 properties and oil-quench hardening procedures. Ensure all machining operations are completed before hardening, as post-hardening modification requires grinding. Follow applicable shop safety protocols when handling and heat-treating tool steel, including proper ventilation and use of appropriate quenching media.\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 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: +0.250 inches, 0.000 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: 2.39 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: 54036\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544435360050,"sku":"54036","price":159.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_e3721180-5049-4d32-a663-4b1e4aa9a7f6.jpg?v=1785926508","url":"https:\/\/voomisupply.com\/products\/starrett-54036-o1-tool-steel-flat-stock-5-32x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
