Ship plate steel, that is, steel for hull structure, is mainly used to manufacture the hull and deck of ocean-going, coastal and inland shipping vessels. The harsh navigation environment of the ship, the hull shell to bear the impact of large wind and waves and alternating loads, coupled with the complex processing and forming technology of the ship, etc., the steel requirements for the hull structure are very strict.

As China moves from a shipbuilding country to a shipbuilding power, ships are developing in the direction of large-scale and lightweight, and the steel materials used are required to be high toughness, high strength, high cleanliness, easy welding and low cost. The use of E-grade shipboard steel has increased year by year, and the strength has also transitioned from general strength to higher strength.
