Q420C Chinese steel grade is a low-alloy high-strength structural steel. It not only is high-strength steel, also is low-carbon steel. Q420C low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Product specification ABS DH40 hull structural steel plate range: thickness 8-650mm, width 1500-4020mm, length 3000-18800mm
12Cr1MoVG high pressure boiler tube belongs to seamless steel tube. The manufacturing method of 12Cr1MoVG high pressure boiler tube is the same as that of seamless steel tube. High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. ABS DH40 hull structural steel plate, 12Cr1MoVG high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good microstructure stability.
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 ABS DH40 hull structural steel plate are higher than that of annealed ABS DH40 hull structural steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of ABS DH40 hull structural steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
