Product Description
AISI 1018 carbon steel bar has a chemical composition of carbon, chromium, manganese, molybdenum, phosphorus, sulfur and silicon. AISI 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. 1018 cold rolled steel bar is made of a general-purpose, low-carbon steel with good case hardening qualities. It is especially suited to cold forming and bending operations. 1018 steel is suitable for parts that require cold forming such as crimping, swaging, or bending. 1018 steel is mild steel with medium-low carbon content. AISI 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. Although its mechanical properties are not very unique, it still can be easily formed, machined, welded and fabricated.
