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, sa573gr.70 carbon steel structural shapes, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
What is the difference between Q345B steel and Q345A steel? sa573gr.70 carbon steel structural shapes, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
Compared with ordinary carbon steel plate, manganese steel plate has the following advantages. First, sa573gr.70 carbon steel structural shapes, manganese steel plate is convenient for welding and processing. Second, manganese steel plate has good heat resistance, and can be processed into various containers. Third, manganese steel plate has good toughness. It is not easy to fracture and has long service life. Fourth, the performance of manganese steel plate is good at low temperature. It will not fracture because of temperature, so it can be used in cold areas.
