Manufactured from AISI Type O1 tool steel, this flat stock measures 5\/32 inches thick, 1 inch wide, and 18 inches long, with a weight of 0.8 pounds. The tight dimensional tolerances — plus or minus 0.001 inches on thickness — make this material well-suited for applications where ground stock accuracy is required before heat treatment. O1 tool steel is a general-purpose oil-hardening grade valued for its machinability in the annealed state and its ability to hold sharp edges and close tolerances after hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in machine shops, tool and die operations, and precision fabrication environments. Typical applications include punch and die components, jigs, fixtures, gauges, and small cutting tools. The 18-inch length and 1-inch width provide a workable blank for layout and machining before hardening. Tool and die makers, machinists, and metalworking professionals are the primary users of this material. It is supplied in the annealed condition, ready for machining prior to oil-quench heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable machinability in the annealed state\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise pre-hardened dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.005 inches under nominal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches from nominal 18 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWeighs 0.8 pounds — manageable single-piece blank for bench work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications requiring oil-quench heat treatment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of O1 tool steel flat stock should be performed in the annealed state prior to heat treatment. Oil-quench hardening requires proper furnace equipment and quench media — this process should be performed by a qualified heat treater or tool and die professional. Follow applicable shop safety practices for handling tool steel during cutting, grinding, and heat treatment operations. Always allow the workpiece to reach ambient temperature before final inspection of tolerances.\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: 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 minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 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: 0.8 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: 54030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540127777074,"sku":"54030","price":76.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_8c38f982-24f6-4568-9737-e6fa5615e3ef.jpg?v=1785846445","url":"https:\/\/voomisupply.com\/products\/starrett-54030-o1-tool-steel-flat-stock-5-32x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
