Manufactured to AISI Type C1018 specification, this flat stock delivers consistent material composition and predictable machinability, making it a reliable starting point for fabricated components, brackets, plates, and structural reinforcements. At 10.2 pounds per piece, it carries substantial mass for its size. Tolerances are held tight: thickness and squareness are controlled to plus or minus 0.001 inches, width tolerance runs plus 0.000 to 0.005 inches, and length tolerance is plus 0.625 inches. These controlled tolerances reduce secondary machining time on precision work.\u003c\/p\u003e\u003cp\u003eC1018 flat stock at this size is commonly used in light fabrication shops, maintenance and repair operations, and trade environments where a machinable, weldable mild steel bar is needed without the cost of a higher-alloy grade. Typical applications include mounting plates, frame gussets, fixture bases, and custom support structures. It suits both manual and CNC machining operations and accepts standard welding processes including MIG, TIG, and stick. The 6-inch width and 24-inch length make it usable as-cut for many common part geometries without additional saw work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI C1018 low carbon steel for consistent machinability and weldability\u003c\/li\u003e\n\u003cli\u003eThickness and square tolerance held to plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for close-fit applications\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.625 inches — never short\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat bar requiring no additional surface preparation for most shop applications\u003c\/li\u003e\n\u003cli\u003eShips as a single piece with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose mild steel flat bar suitable for fabrication, machining, and structural applications where AISI C1018 low carbon steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, drilling, and welding of mild steel flat stock should be performed by qualified machinists or fabricators using appropriate personal protective equipment. Secure the workpiece firmly before any cutting or drilling operation. When welding, follow applicable AWS guidelines and ensure adequate ventilation.
