O1 tool steel is an oil-hardening, cold-work alloy known for its good wear resistance, dimensional stability during heat treat, and ease of machining in the annealed state. This flat stock ships in the annealed condition and is intended for tool and die makers, machinists, and metalworking shops that need a reliable, precision-ground blank for punches, dies, gauges, knives, and other tooling components. Weight is 1.59 pounds per piece. Thickness and squareness tolerances are held to tight commercial standards suitable for direct use in tooling applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in job shops, tool rooms, and production environments where a machinable, hardenable blank is required. Typical applications include fabricating punches, arbors, cutting tools, fixture components, and custom hand tools. The annealed condition allows conventional milling, turning, and grinding before the final oil-quench hardening cycle. It is well-suited for low-to-medium production tooling where D2 or A2 alloys would be excessive and carbon steel lacks sufficient hardness potential.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — machines readily in annealed state, hardens via oil quench\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for predictable fit in tooling slots\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches — stock is never short\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock suitable for general toolroom and die shop use wherever AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and hardening of tool steel flat stock is performed by qualified machinists and tool and die makers. Work the stock in the annealed condition using conventional cutting and grinding equipment before hardening. Follow the material supplier heat-treat guidelines for the O1 alloy preheat, austenitizing temperature, and oil-quench procedure — do not substitute water quench. Wear appropriate PPE when handling and heat-treating tool steel bar stock.\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: 1 inch\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, minus 0 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: 1.59 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542231482674,"sku":"54326","price":139.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_f5d03d18-9178-4417-8f65-8aa2de39a6cc.jpg?v=1785895791","url":"https:\/\/voomisupply.com\/products\/starrett-54326-o1-tool-steel-flat-stock-5-32x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
