They are also often employed in pipeline construction for the transportation of liquids and gases. Other common uses include power plants and other energy-generation equipment. Their resistance to corrosion helps ensure they can continue working reliably for long periods of time, even in harsh environments.

Corrosion Resistance

Q345B carbon steel plate possesses good corrosion resistance, making it suitable for use in harsh environments. The plate is also able to withstand high levels of stress and pressure without buckling or breaking, which makes it ideal for structural applications.

The corrosion resistance of Q345B steel can be enhanced through shot peening, a process that involves delivering projectiles to the surface of the metal. This causes small particles to form on the surface of the steel, which changes its morphology and enhances its corrosion resistance. This study used Q345B steel to Q345B carbon steel plate investigate the effects of ultrasonic shot peening on its surface roughness, microhardness and corrosion resistance. The results showed that the microhardness and corrosion resistance of the steel improved after USP treatment, and the surface roughness was significantly reduced.

Q345B steel is a type of Chinese low alloy, medium tensile strength steel that is rolled using a hot rolling process. This type of steel is commonly used for general purpose manufacturing, including sheet metal and light structural elements in household goods. The material meets international standards, such as GB/T 1591-2008, and adheres to strict quality requirements. Its versatility and performance make it an attractive choice for a wide range of industrial and commercial applications. Its strong load-bearing capacity and structural integrity make it a popular choice for building construction projects, such as bridges, vehicles and power stations.

Welding Properties

Q345B carbon steel plates can be welded to create a strong and durable construction. This type of plate is used in applications that require high load bearing and structural integrity. It is also resistant to corrosion and abrasion, making it suitable for storing liquids and gases. Q345B plates are also commonly used in the fabrication of storage tanks and containers for various industries.

During welding, it is important to control the temperature to avoid cold cracks and loss of toughness in the galvanized steel coil manufacturers weld region. This can be achieved by using a controlled welding process and selecting an appropriate electrode for the job. It is also necessary to monitor the weld surface to ensure that it meets quality standards.

The hardness distribution curves of R0, R1, and R2 welds are shown in Fig. 10. It can be seen that the hardness of the weld increased first and then decreased due to the decrease in d-ferrite morphology and grain size. Nevertheless, the hardness of the weld improved over time and approached that of the base material.

Besides the high tensile strength, Q345B steel plates have good formability and welding properties. This makes them ideal for structural and piping applications. This grade is able to withstand extreme stress and pressure while maintaining its structural integrity. It is often used in building construction to reinforce critical areas such as columns and beams.
