O1 is an oil-quench tool steel known for excellent machinability in the annealed state and good wear resistance after hardening. This flat stock ships in an annealed condition, making it machinable before heat treatment. It is used by tool and die makers, machinists, and fabricators who need a reliable, dimensionally consistent stock piece for shop work, jigs, fixtures, dies, and cutting tools. The piece weighs approximately 30.92 pounds.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabrication and tooling applications in machine shops, tool rooms, and industrial manufacturing environments. The oversized length and width tolerances allow the end user to machine to final net size, while the tight thickness tolerance of plus or minus 0.001 inches supports applications where consistent cross-section is critical. It is appropriate for both one-off custom tooling and short-run die work where O1 grade steel is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for good machinability and post-hardening wear resistance\u003c\/li\u003e\n\u003cli\u003eThickness of 0.25 inches held to a tight tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth of 12 inches with a tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eLength of 36 inches with a plus 0.5 inch length tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches; squareness: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity for flexible procurement\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 dies, punches, jigs, fixtures, gauges, and similar tooling applications where AISI Type O1 material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate cutting tools and coolant. Always follow established shop safety practices when cutting, grinding, or hardening tool steel.
