The yield strength of AH36, DH36, CCSB bulk cargo ship steel, EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa. The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively. The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa.
The addition of Ca element in steel such as CCSB bulk cargo ship steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
It is not the thicker the steel plate is, the better. The larger steel plate thickness means higher price and purchase cost, and it is also not inconvenient for transportation. Besides, the thickness of CCSB bulk cargo ship steel, steel plate has relation to the safety, so the thickness of steel plate is not determined at random, and the size data of steel plate should be strictly planned according to the requirements of drawings. Therefore, it is necessary to select the appropriate steel plate material and specification according to the use.
