Shipbuilding steel
Shipbuilding steel is used in the manufacture of sea-going ships and large inland hull structure steel. Due to the hull structure commonly used welding method, so the requirement of shipbuilding steel has good welding performance. In addition, it also requires a certain strength, toughness and low temperature and corrosion resistance. In the past mainly adopts low carbon steel for shipbuilding steel. Recently, has a large number of using common low alloy steel, the existing 12 vessel, 16 manganese steel such as ship 15 manganese, vanadium, such as steel. These steel with high strength, good toughness, easy machining and welding, sea water corrosion resistance and other comprehensive features, can be successfully used to produce ten thousand tons of ocean-going ships
