C1018 is a general-purpose mild steel valued for its consistent machinability, weldability, and moderate strength, making it a go-to stock material for fabrication shops, maintenance departments, and trade professionals who need reliable raw bar stock for custom parts, brackets, shims, and structural components. At 11.9 pounds per piece, this flat bar delivers solid mass for demanding shop and field applications.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for a wide range of fabrication and maintenance tasks in commercial, industrial, and trade settings. Common applications include machining custom brackets, cutting shim stock, welding structural supports, and general metalworking where tight dimensional tolerances are required. The C1018 specification makes it compatible with MIG, TIG, and oxy-fuel welding processes and accepts standard threading, drilling, and milling operations without special tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type C1018 low carbon steel for consistent machinability and weldability\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fit-up\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.625 inches from nominal 24-inch length\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003eReady-to-use flat bar format — no additional forming required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI C1018 low carbon steel flat stock for general fabrication, machining, and structural applications across industrial and trade environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting, drilling, and welding of C1018 steel flat stock should be performed by qualified metalworkers or trade professionals using appropriate PPE including eye protection and gloves.
