Marine Cold Rolled Steel Round Bar

Cold Rolled Steel Round Bar Production

The production of a cold rolled steel round bar begins with a hot rolled steel bar. The hot rolled steel bar is obtained through a process called hot rolling, where the steel is heated to high temperatures and passed through a series of rollers to achieve the desired shape and size.

Once the hot rolled steel bar is obtained, it undergoes the cold rolling process. This process involves passing the hot rolled steel bar through a set of rollers at room temperature. The roller exerts pressure on the steel bar, reducing its thickness and elongating its length. The process is typically performed in multiple passes to achieve the desired dimensions and properties.

One of the primary advantages of cold rolling is the improvement in dimensional accuracy. The process allows for precise control over the diameter, length, and straightness of the round bar, ensuring consistency in the final product. Cold rolling also enhances the surface quality of the round bar, resulting in a smoother and more refined finish.

The cold rolling process imparts several mechanical property improvements to the steel round bar. It increases the material’s tensile strength, making it stronger and more resistant to deformation under load. The process also enhances the hardness, toughness, and yield strength of the steel, further improving its mechanical performance.

Most Porpular Cold Rolled Bar – 1018 Round Bar

The most popular cold rolled bar in marine applications is the 1018 marine steel round bar. The 1018 steel is a widely used low carbon steel that offers excellent versatility, strength, and machinability, making it a preferred choice for various marine-related projects.

1081 Round Bar Features

The 1018 round bar is made from low carbon steel, also known as mild steel, which offers a good balance of strength, ductility, and affordability. Here are some key characteristics and features of the 1018 round bar:

• Composition: The 1018 round bar is primarily composed of iron (Fe) and carbon (C). It typically contains around 0.15% to 0.20% carbon, which gives it its low carbon designation. It may also contain small amounts of other elements such as manganese (Mn), phosphorus (P), and sulfur (S).
• Strength and Ductility: The 1018 round bar exhibits moderate strength, making it suitable for various applications. While it may not have the highest tensile strength, it offers good ductility, allowing it to deform without fracturing under stress. This combination of strength and ductility makes it versatile for different engineering purposes.
• Machinability: One of the notable advantages of the 1018 round bar is its excellent machinability. It can be easily cut, drilled, turned, and milled using common machining processes. This makes it a preferred choice for applications that require precise shaping and customization.
• Weldability: The 1018 round bar is known for its good weldability. It can be welded using different methods, such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). Its weldability allows for efficient joining and fabrication processes.
