Type of Sub-products

Hot Rolled 1018 Carbon Steel Round Bar Hot Rolled 1018 Carbon Steel Round Bar
Hot rolled 1018 carbon steel round bars are produced at high temperatures, resulting in a scaled surface and less precise dimensions. They are economical and widely used in applications where surface finish is not critical, such as structural supports and general fabrication. Their strength makes them suitable for heavy-duty uses.

Cold Drawn 1018 Carbon Steel Round Bar Cold Drawn 1018 Carbon Steel Round Bar
Cold drawn 1018 carbon steel round bars are manufactured by drawing the steel through dies at room temperature, resulting in improved dimensional accuracy and a smoother finish. These bars offer better tensile strength and hardness, making them ideal for precision components like shafts and pins.
