The working environment of ships is harsh, and the hull shell is subject to chemical and electrochemical corrosion from seawater, as well as corrosion from marine organisms and microorganisms; The hull is subjected to significant wind and wave impacts and alternating loads; Due to factors such as the complex processing method caused by the shape of the ship, strict requirements are placed on the steel used for the hull structure. Firstly, good toughness is the most critical requirement. In addition, it requires high strength, good corrosion resistance, welding performance, processing and forming performance, and surface quality. To ensure quality and sufficient toughness, it is required that the chemical composition of Mn/C should be above 2.5, and there are strict requirements for carbon equivalent, which should be produced by a steel factory recognized by the ship inspection department. Structural steel for ship hulls is classified into strength levels based on its minimum yield point: general strength structural steel and high-strength structural steel. Structural steel for ship hulls is divided into two types: general strength steel and high-strength steel. General strength steel is divided into four grades based on quality: A, B, D, and E; High strength steel is divided into two strength levels and three quality levels; AH32, DH32, EH32, AH36, DH36, EH36.
