Manufactured to AISI Type O1 specification, this flat stock measures 0.25 inches thick by 0.25 inches wide by 18 inches long and weighs approximately 0.33 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for precision layout work before hardening and finishing. O1 steel offers excellent machinability in the annealed state and responds predictably to oil-quench hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool rooms, and maintenance departments in light industrial and manufacturing environments. It is a practical choice when a short, accurate blank is needed for a custom punch, form tool, scraper blade, or similar small tooling component. The 18-inch length allows one or more parts to be cut from a single piece depending on finished part length. Typical users are toolmakers and machinists working to print dimensions, as well as prototype shops sourcing small quantities of precision tool steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel  -  machines cleanly in the annealed state and hardens with an oil quench\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches provides reliable minimum-width assurance\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches ensures full nominal length is met\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches across the cross-section supports accurate layout without additional grinding\u003c\/li\u003e\n\u003cli\u003eCompact 0.33-pound piece weight  -  convenient for bench stock and small-quantity tooling work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general toolmaking, die work, and precision part fabrication requiring oil-quench hardenable stock in a 0.25-inch by 0.25-inch cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by a qualified machinist or toolmaker using appropriate personal protective equipment and machine guards. O1 steel is supplied in the annealed condition; heat treatment including hardening and tempering must be performed by qualified personnel following recognized metallurgical procedures before placing finished parts into service. Deburr all cut edges before handling.
