Type of Sub-products
Hot Rolled 1030 Carbon Steel Round Bar Hot Rolled 1030 Carbon Steel Round Bar
Hot rolled 1030 carbon steel round bars are manufactured at high temperatures, resulting in a rough surface finish and less precise dimensions. They are economical and suitable for applications where exact measurements are not critical, such as construction and heavy fabrication. Their strength makes them reliable for structural uses.
Cold Drawn 1030 Carbon Steel Round Bar Cold Drawn 1030 Carbon Steel Round Bar
Cold drawn 1030 carbon steel round bars are processed at room temperature, which improves their dimensional accuracy and surface smoothness. These bars have higher tensile strength and hardness, making them ideal for precision engineering parts like shafts and gears. Their enhanced mechanical properties suit demanding applications.
