Carbon Steel Rectangle Bar 1018 Precision Ground

Show full description

Carbon Steel Rectangle Bar 1018 Precision Ground

The 1018 precision-ground carbon steel rectangle bar is a low-carbon alloy that offers excellent weldability and ease of machining. These bars are widely used for mounting plates, machinery bases, and general-purpose mechanical parts requiring a smooth finish. The precision-ground process ensures the material is perfectly flat and within very tight dimensional tolerances for immediate assembly. 1018 carbon steel is the most common choice for general fabrication due to its versatility and balanced mechanical properties. Order your precision-ground 1018 from Onlinemetals.com for a clean, professional starting point for your next engineering project.
