Manufactured to AISI Type O1 material specification, this flat stock measures 1\/32 inch thick, 1-1\/2 inches wide, and 18 inches long. Thickness and squareness tolerances are held to plus or minus 0.001 inch, making it suitable for applications where dimensional accuracy before hardening matters. Machinists, tool and die makers, and fabricators working in job shops or maintenance environments typically stock this material for custom tooling and fixture components.\u003c\/p\u003e\n\u003cp\u003eO1 tool steel is a general-purpose oil-hardening grade known for its good machinability in the annealed state and its ability to hold a keen edge after hardening and tempering. This flat stock is appropriate for producing small punches, blades, gages, and similar toolroom parts where moderate toughness and wear resistance are required. The 18-inch length provides sufficient stock for multiple short workpieces. At 0.24 pounds per piece, handling and storage are straightforward for bench or rack stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat-treat response\u003c\/li\u003e\n  \u003cli\u003eThickness of 1\/32 inch with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eWidth of 1-1\/2 inches with tolerance of minus 0.000 to minus 0.005 inch\u003c\/li\u003e\n  \u003cli\u003eLength of 18 inches with plus 0.250 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eSquareness held to 0.003 inch per inch on all edges\u003c\/li\u003e\n  \u003cli\u003eSupplied in annealed condition, ready for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat stock suitable for general toolroom, die shop, and precision fabrication use where O1 grade material in this size is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining should be performed in the annealed state before heat treatment. Follow established AISI O1 hardening and tempering procedures, including proper preheat, austenitizing, and oil quench steps.
