Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, LR grade A passage ship steel, ABS EH36 plate is the most critical requirement In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality,LR grade A passage ship steel.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.

Q345 and Q345B are steel numbers. The differences are as follows:
1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.
2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).
3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.
Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

The alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62 Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties They are fully used within 500°C,LR grade A passage ship steel.
