Shipbuilding Steel main application is to make shipbuilding, inland hull structure and ship repairing, shipbuilding Steel usually as high quality carbon steel and low alloy steel.According to the use, can be divided into steel plate,Flat-bulb steel,Flat bar,angle steel,steel pipes and steel bars,The main classification society we cooperate are: ABS ,GL, LR, BV, NK,DNV,KR,RINA.
Shipbuilding Steel has certain strength, toughness and low temperature resistance and corrosion resistance, and has good welding performance.
Shipbuilding structural steel has include general strength and high strength steel,According to the quality, the general strength steel is divided into four grade:A, B, D and E grade; the high strength steel is divided into two level and three grades: AH32, DH32, EH32, AH36, DH36, EH36.
