Conforming to AISI Type O1 material specification, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 inches to 0.000 inches. It is used in toolmaking, fixture building, die work, and precision machining applications where dimensional consistency before heat treatment is critical. Machinists, toolmakers, and industrial fabricators are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for shop environments where custom tooling components, punches, dies, gauges, blades, or wear parts are being fabricated from raw stock. The 36-inch bar length provides enough material for multiple shorter blanks, and the pre-sized cross-section reduces initial stock removal. O1 grade is well-regarded for its machinability in the annealed state and its ability to hold close tolerances after oil quenching during heat treatment. It is appropriate for both one-off toolroom use and small-batch production of tool components.\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 of 0.25 inches with a tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth of 0.75 inches with a tolerance of plus 0.005 inches to 0.000 inches\u003c\/li\u003e\n\u003cli\u003eLength of 36 inches with a tolerance of plus 0.5 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.003 inches on edges; 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eFlat stock form allows direct use as blank stock for tooling and die components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a raw material flat stock blank for general toolroom and fabrication use where AISI O1 oil-hardening tool steel is specified.\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. Standard metalworking equipment including band saws, surface grinders, and milling machines are appropriate for stock preparation.
