Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For GL-F32 cargo barge steel plate medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
The yield strength of AH36, DH36, GL-F32 cargo barge steel plate, 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.
Among them, Russia's crude steel output was 71.6 million tons, down 0.7% year on year; Ukraine's crude steel output was 20.8 million tons, down 1.2% year on year. GL-F32 cargo barge steel plate, Crude steel production in the Middle East was 45.3 million tons, up 19.2% year on year. The annual output of crude steel in South America is 41.2 million tons, down 8.4% year on year.
