AISI Type O1 is a general-purpose oil-hardening tool steel valued for its dimensional stability during heat treatment and its ability to hold a keen edge after hardening. This flat stock is supplied in the annealed condition, ready for machining to finished dimensions before hardening. Machinists, toolmakers, and die makers use it to fabricate punches, dies, gauges, bushings, and cutting tools in both production and job-shop environments. The piece weighs approximately 11.47 pounds.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited to applications where tight dimensional tolerances are required before and after heat treatment. Typical uses include the fabrication of blanking and forming dies, jigs and fixtures, precision gauges, and wear-resistant machine components. The 3\/16 inch thickness makes it appropriate for thin-section tooling such as blanking plates, shim stock replacements, and slender blade-form tools. It ships as a single 36-inch length and is commonly worked with standard milling, grinding, and EDM equipment found in tool and die shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel — good machinability in the annealed state, stable geometry through oil-quench heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.015 inches, zero minus — stock is never undersized in length\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for predictable fit in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat bar suitable for use wherever O1 ground flat stock is specified in tooling, die-making, and precision machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO1 tool steel flat stock is machined, ground, or EDM-processed in the annealed condition prior to hardening and tempering. Always follow established heat-treatment procedures for AISI O1 including proper preheat, austenitizing temperature, and oil-quench sequence — consult the steel manufacturer's data sheet for thermal cycle parameters. Wear appropriate PPE when cutting or grinding tool steel. Inspect finished dimensions after grinding to verify tolerance compliance before committing the blank to heat treatment.\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: 3\/16 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, zero minus\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: 11.47 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538921816370,"sku":"54350","price":366.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_394f000b-394e-4b16-a6df-beefea2de628.jpg?v=1785829726","url":"https:\/\/voomisupply.com\/products\/starrett-54350-o1-tool-steel-flat-stock-3-16x6x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
