O1 is an AISI-designation oil-hardening tool steel widely used in toolmaking, die work, and precision machining applications where consistent hardness and dimensional accuracy are required. This flat stock ships in an annealed (soft) condition, allowing machinists and toolmakers to cut, grind, and shape it before hardening. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications that demand close starting tolerances before final grind. The bar weighs approximately 1.94 pounds.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, machine shops, and metalworking facilities for fabricating punches, dies, gauges, jigs, fixtures, and similar tooling components. It is an appropriate choice for short-run tooling where oil-quench hardening is the preferred heat-treat method. Machinists, toolmakers, and die makers are the primary installers and end users of this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for consistent through-hardening with an oil quench\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for tight dimensional control\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, zero minus, ensuring stock is never undersized in length\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 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 machining, filing, and grinding prior to heat treatment\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 general toolmaking and die-making applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, drilling, and grinding should be performed while the stock is in the annealed condition before heat treatment. Heat treating O1 tool steel requires controlled atmosphere or salt-bath furnace equipment and should be performed by a qualified heat treater or machinist familiar with oil-quench hardening procedures. Always wear appropriate PPE when cutting or grinding tool steel. Consult applicable shop safety standards and equipment manufacturer guidelines during all machining and heat-treat operations.\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: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches, zero minus\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: 1.94 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: 54284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540150124850,"sku":"54284","price":179.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_e1bf118b-9dc1-49de-8172-9c468ccdbe35.jpg?v=1785847182","url":"https:\/\/voomisupply.com\/products\/starrett-54284-o1-tool-steel-flat-stock-3-32x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
