TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the marine grade KD32 hull steel plate steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
Oxygen is a harmful element in marine grade KD32 hull steel plate steel. With the increase of oxygen content, the strength of marine grade KD32 hull steel plate steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of marine grade KD32 hull steel plate steel.
ABS class shipbuilding steel plate contains two kinds as common strength and high strength ship plate according to different yield and tensile strength.Common strength shipbuilding plates Grade A, B, D, E and F are mainly used to contribute hull of ship,and high strength shipbuilding plate are mainly built the cranes of bulk and breaker ships in low temperature surroundings. ABS Grade AH36, DH36, marine grade KD32 hull steel plate, and EH36 plate rolling specifications range:Thickness within 3-300mm,Width within 1250-4000mm.
