Conforming to AISI Type O1 specifications, this flat stock is supplied in an annealed condition suitable for machining, grinding, and subsequent oil-quench hardening. Key controlled dimensions are 7\/16 inches thick, 6 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches and a length tolerance of plus 0.015 inches. Weighing 26.77 pounds, it is heavy enough to require proper material handling during setup and fixturing.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, moldmaking operations, and precision machining environments where O1 tool steel is specified for punches, dies, gauges, fixtures, blades, and general tooling blanks. The 6-inch width and 36-inch length make it well suited as a starting blank for larger dies, parallels, or flat tooling components that are subsequently heat treated by oil quenching to achieve working hardness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel material specification\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance machining\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of minus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows full machining prior to heat treat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock blank for tool and die, moldmaking, and precision machining applications where AISI Type O1 oil-hardening tool steel is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate personal protective equipment and machine guarding. Oil quench hardening requires a controlled heat treat process typically performed by a qualified heat treater or in a properly equipped shop furnace — do not attempt hardening without proper equipment and thermal controls. Secure the bar firmly in a vise or fixture before sawing or milling operations. Follow applicable shop safety codes and material handling guidelines when moving stock of this weight.\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: 7\/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: minus 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 26.77 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: 54436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539455476018,"sku":"54436","price":947.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_a66b769d-2807-44e5-b94b-54cc38d13faa.jpg?v=1785840607","url":"https:\/\/voomisupply.com\/products\/starrett-54436-o1-tool-steel-flat-stock-7-16x6x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
