Manufactured from AISI Type O1 tool steel, this flat stock measures 0.75 inches thick, 8 inches wide, and 36 inches long, with a finished weight of 61.2 pounds. O1 tool steel is a cold-work, oil-quenching grade known for its excellent machinability in the annealed state and its ability to hold a keen edge after hardening. Thickness and squareness tolerances are held to tight limits, making this stock suitable for applications where dimensional consistency matters before and after heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in shops producing punches, dies, gauges, cutting tools, and precision fixtures. The large 8-inch width and 36-inch length allow machinists and toolmakers to cut multiple blanks from a single piece, reducing material waste. It is appropriate for both production toolrooms and job shops. Typical end users include tool and die makers, machinists, and metalworking fabricators who require consistent, predictable steel that responds well to conventional machining operations prior to oil quenching 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\u003eTight thickness tolerance of plus or minus 0.001 inches for dimensional consistency\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.005 inches under nominal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLarge 8 by 36 inch format allows multiple blanks to be cut from one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolmaking, die making, and precision fixture applications where annealed machinability and oil-quench hardenability are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment.
