What is marine grade steel plate?
Marine Grade Steel is a type of structural alloy steel which is standardized by the American Bureau of Shipping (ABS) for specific use in the ship building industry. This group of alloy steel is engineered to be stronger and able to withstand harsh marine conditions.
What are marine grade carbon steels?
There are various Carbon steel grades available such as AH36, DH36, and EH36, that are commonly used in marine environments. These grades have more alloying elements like chromium and manganese that offer more strength and corrosion resistance. These grades are approved by the American Bureau of Shipping.

Application
Carbon hot rolled steel sheets and plates are used in the welding and construction sectors such as railroad tracks, construction equipment, boom cranes, agriculture equipment and heavy vehicle frames. By varying the percentage in carbon steel, it is possible to produce steel with a variety of different qualities. In general, higher carbon content in steel makes steel harder, brittler and less ductile.
Carbon cold rolled steel coils and strips are produced with a highly adaptable manufacturing process, which are extensively used in automobile, washing machines, refrigerators, electrical appliances and steel office equipment. By varying the percentage in carbon steel, it is possible to produce steel with a variety of different qualities. In general, higher carbon content in steel makes steel harder, brittler and less ductile.
