O1 is an AISI-specified oil-hardening grade tool steel widely used in toolmaking, die making, and precision machining applications where controlled heat treatment and high hardness are required after hardening. This flat stock is supplied in the annealed condition, ready for machining to final dimensions before oil-quench hardening. The piece weighs 102 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications that demand tight dimensional control before heat treat.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, machine shops, and industrial fabrication environments. Typical applications include blanking dies, forming dies, punches, gauges, and custom tooling fixtures. The 1 inch thickness and 10 inch width make this a large-format bar suited to heavier tooling components. It is typically worked by skilled machinists or toolmakers using conventional milling, turning, or surface grinding equipment prior to hardening and tempering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise pre-grind allowances\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, zero minus for reliable cut-to-length stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 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\u003eLarge-format bar at 1 inch x 10 inches x 36 inches suits heavy die and tooling work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat stock suitable for toolmaking, die making, and precision machining applications requiring oil-quench heat treatment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and hardening of tool steel flat stock should be performed by qualified toolmakers or machinists familiar with O1 heat treat procedures. Always follow appropriate shop safety protocols when cutting, grinding, or heat treating tool steel. Personal protective equipment including eye protection and heat-resistant gloves is required during hardening operations. Consult the material specification and your heat treat facility for proper austenitizing temperature, quench medium, and tempering guidelines specific to AISI O1.\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\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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 0.015 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 on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 102 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: 54512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540241776946,"sku":"54512","price":1955.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_873c9613-5d76-4ebb-95af-42080e64b1c2.jpg?v=1785849962","url":"https:\/\/voomisupply.com\/products\/starrett-54512-o1-tool-steel-flat-stock-1x10x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
