Conforming to AISI Type O1 specification, this flat stock measures 0.25 inches thick, 2 inches wide, and 36 inches long, with a weight of 5.16 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications that demand close dimensional control. Width tolerance is plus 0.005 inches, minus 0.000 inches. Length tolerance is plus 0.5 inches. O1 tool steel is known for its good machinability in the annealed state and its ability to achieve high hardness after oil quench.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, machine shops, and maintenance departments for fabricating punches, dies, gauges, jigs, fixtures, and cutting tools. It is appropriate for both prototype and production work where dimensional accuracy and hardenability are required. The 36-inch length allows for single-piece or segmented blanks depending on the application. Machinists and toolmakers working with manual or CNC equipment will find this stock suitable for operations such as milling, grinding, and drilling prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel construction\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for close-tolerance work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e36-inch length with plus 0.5-inch length tolerance\u003c\/li\u003e\n\u003cli\u003eGood machinability in annealed condition prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock suitable for general tool and die fabrication, gaugemaking, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures.
