You know the characteristics of ship plate it?

Poor working conditions of the ship, the hull shell to chemical corrosion by seawater, sea creatures and electrochemical corrosion, microbial corrosion; hull to withstand greater shock waves and alternating load; ship shaped to complex processing methods and other factors, so the hull structural steel demanding. First good toughness is the most critical requirement, in addition, requires a high strength, good corrosion resistance, weldability, molding properties and surface quality. To maintain quality and ensure that there is sufficient toughness required chemical composition Mn / C at 2.5 or more on the carbon equivalent, there are strict requirements, ship inspection departments approved by the production of steel. Hull structural steel division intensity level in accordance with the minimum yield point: the general strength structural steel and high-strength structural steel.
