Manufactured to AISI Type O1 specification, this flat stock measures 1\/32 inch thick, 3\/4 inch wide, and 18 inches long, with a thickness tolerance of plus or minus 0.001 inches. O1 tool steel is a general-purpose oil-hardening grade known for good dimensional stability during heat treatment and moderate wear resistance. Machinists, tool and die makers, and precision fabricators use this material as raw stock for cutting tools, punches, gauges, and fixtures.\u003c\/p\u003e\n\u003cp\u003eThis flat stock suits applications in machine shops, tool rooms, and fabrication shops where tight dimensional tolerances and consistent material properties are required in the annealed condition. The 18-inch length provides enough stock for multiple short-run parts or a single longer component. The 1\/32-inch thickness makes it well suited for thin shims, blades, or liner stock requiring precision ground dimensions prior to heat treatment. Width tolerance is held to 0.000 to negative 0.005 inches, and length tolerance is a positive 0.250 inches, accommodating standard saw-cut finishing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel for stable, predictable hardening response\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for tight fit-up applications\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of 0.000 to negative 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of positive 0.250 inches suitable for standard cut-to-length stock\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 before oil-quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose O1 tool steel flat bar for use in tool rooms, die shops, and precision fabrication environments requiring AISI Type O1 oil-hardening material in flat stock form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and finishing of O1 tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate cutting tools and coolant. Heat treatment, including hardening and tempering, requires controlled oven equipment and oil-quench facilities and should follow standard AISI O1 heat treat procedures. Always wear appropriate personal protective equipment when cutting, grinding, or heat treating tool steel. Follow applicable shop safety codes and procedures when handling hardened or sharp-edged stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1\/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: 18 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 negative 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: positive 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 53934\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538324095282,"sku":"53934","price":68.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_e5cfa50f-075d-429b-abec-b666454b1dd4.jpg?v=1785823036","url":"https:\/\/voomisupply.com\/products\/starrett-53934-o1-tool-steel-flat-stock-1-32x3-4x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
