Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized LR EH36 hull construction steel are higher than that of annealed LR EH36 hull construction steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of LR EH36 hull construction steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The steel used for offshore platforms in various countries in the world is divided into mild steel, medium-high-strength steel and high-strength steel. At the same time, considering the stability and reliability of offshore platform components, steels of different strengths need to meet different yield ratios. In addition, due to the different parts used on the offshore platform, the thickness requirements of the steel plate are also different.
