What is the steel material used for the hull

The hull can be divided into main body and superstructure. The main part generally refers to the part below the upper deck, which is a hollow body with specific shape enclosed by the hull and upper deck. It is the key part to ensure the required buoyancy, navigation performance and hull strength of the ship. It is generally used to arrange power plants, load goods, store fuel and fresh water, and arrange other cabins. The superstructure is located in the cabin surrounded by the upper deck, which is mainly used for various purposes.

The hull structure is composed of steel plates and profiles, which can be divided into longitudinal skeleton structure, transverse skeleton structure and hybrid skeleton structure. There are thousands of ship parts, which are made of many kinds of materials, especially steel. Carbon steel and low alloy high strength steel are the main materials for hull structure.
