Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of A514 Gr E quenched and tempered steel high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.
