Conforming to AISI Type O1 material specification, this flat bar measures 1\/8 inch thick, 10 inches wide, and 36 inches long, with a finished weight of 12.76 pounds. Thickness and squareness tolerances are held to plus or minus 0.001 inches, making it suited for applications where dimensional accuracy is critical before heat treat. Machinists, tool and die makers, and metal fabricators work with this stock to produce punches, dies, gauges, and similar precision tooling components.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock of this size is used primarily in job shops, tool rooms, and production environments where blanks must be cut, ground, and machined to final form before oil-hardening heat treatment. The 10-inch width and 36-inch length provide substantial material for multiple blanks from a single piece. This grade is widely specified for low-distortion oil-quench applications where moderate wear resistance and good machinability in the annealed state are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for precision blank preparation\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.0000 to minus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eFinished bar weight of 12.76 pounds for a single piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar suitable for toolmaking, die making, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be performed in the annealed condition prior to heat treatment.
