High-strength hull structural steel is smelted by adding a small amount of alloying elements such as manganese, niobium, vanadium, aluminum and silicon on the basis of general-strength hull structural steel. Its strength, mechanical properties, weldability, corrosion resistance and wear resistance. The performance and other indicators are better than the general strength hull. According to its minimum upper yield strength, it is divided into three strength levels, namely, 32kg, 36kg, and 40kg. 1 intensity level, 4 quality levels.
The H (high) symbol is added after the quality grade to distinguish the general strength AH36, DH36, EH36, FH36. Yield strength of AH32, DH32, EH32, FH32> 315 MPa, tensile strength 440-570 MPa; Yield strength of AH36, DH36, EH36, FH36> 355 MPa, tensile strength 490-630 MPa: AH40, DH40, EH40, The yield strength of FH40 is 2390 MPa, and the tensile strength is 510-660 MPa.
