Manufactured to AISI Type O1 specification, this flat stock measures 7\/32 inches thick, 1 inch wide, and 36 inches long, weighing 2.23 pounds. Thickness and squareness tolerances are held to plus or minus 0.001 inches, making it suitable for applications where dimensional consistency is critical before hardening. Licensed machinists, toolmakers, and die makers work with this material to fabricate punches, dies, gauges, and cutting tools that will be heat treated after machining to final form.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is a common starting material in job shops, tool rooms, and maintenance departments. The 36-inch length provides enough stock to yield multiple smaller blanks from a single piece. The 1-inch width and 7\/32-inch thickness are standard proportions suited to small punch blanks, flat gauge stock, and thin die components. Edge squareness is held to 0.003 inches per inch across all edges, supporting accurate layout and setup work directly off the bar.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — machines readily in the annealed state and hardens in oil quench\u003c\/li\u003e\n\u003cli\u003eThickness: 7\/32 inches with plus or minus 0.001-inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 1 inch with tolerance of 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength: 36 inches with plus 0.015-inch tolerance\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWeight: 2.23 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar for toolroom, die shop, and precision machining applications requiring annealed stock that will be machined and then oil-quench hardened.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment by qualified machinists or toolmakers. Follow established shop safety practices including eye and hand protection when sawing, milling, or grinding. Heat treatment to harden O1 steel requires controlled furnace temperatures and an oil quench — this work should be performed by personnel familiar with tool steel heat treatment procedures and applicable shop safety codes. Allow stock to return to ambient temperature before precision measurement to ensure accurate readings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type O1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 7\/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\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: 2.23 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: 54355\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539035324722,"sku":"54355","price":131.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_542cbbb3-56bc-4b53-adf6-e684fabeffb1.jpg?v=1785833369","url":"https:\/\/voomisupply.com\/products\/starrett-54355-o1-tool-steel-flat-stock-7-32x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
