Manufactured to AISI Type O1 material specification, this flat stock measures 1\/16 inch thick, 3 inches wide, and 18 inches long, with a weight of 0.96 pounds. Thickness tolerance is held to plus or minus 0.001 inches, and edge squareness is controlled to 0.003 per inch, making this stock suitable for applications requiring close dimensional accuracy before hardening. Machinists, tool and die makers, and metal fabricators work with this material regularly.\u003c\/p\u003e\u003cp\u003eO1 oil-hardening tool steel flat stock is used in professional machine shops, toolrooms, and fabrication environments. It is well-suited for making punches, dies, gauges, jigs, and fixtures where a material that can be machined in its annealed state and then oil-hardened to final hardness is required. This piece is sold individually and is intended for direct use or further machining prior to heat treatment.\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: 1\/16 inch with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 3 inches with tolerance of minus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with plus 0.250 inch length tolerance\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 per inch on all edges\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 1 piece per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring annealed stock that will be oil-hardened after machining.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified machinists or tool and die makers familiar with O1 steel properties. Always follow proper safety procedures when grinding, cutting, or machining tool steel, including appropriate PPE for chip and coolant hazards. Oil-hardening heat treatment requires a controlled atmosphere or appropriate quench medium and should follow established metallurgical procedures. Consult applicable shop safety codes before performing heat treatment 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: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\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: minus 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.96 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: 53962\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544629477682,"sku":"53962","price":108.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_04adee98-2c46-48ac-9820-32dde1196237.jpg?v=1785932050","url":"https:\/\/voomisupply.com\/products\/starrett-53962-o1-tool-steel-flat-stock-1-16x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
