    AISI/SAE 1018 Round Steel Bar Description

    The 1018 cold rolled steel bar is crafted from a versatile, low-carbon steel with excellent case hardening qualities, making it well-suited for cold forming and bending operations. This type of steel is particularly suitable for parts requiring cold forming, such as crimping, swaging, or bending. With its medium-low carbon content, 1018 steel is categorized as mild steel. AISI 1018 carbon steel is a free machining grade that is widely available worldwide. While its mechanical properties are not particularly unique, it remains easily formable, machinable, weldable, and fabricable.
