How many categories does the shipbuilding steel are divided?

Posted:2011/10/27 13:31:18

The general intensity hull structural steel is divided into A,B,C,D four levels,all of their yield strength is no less than 235 MPa and their tensile strength is 400-520 Mpa,but their impact energy is different which is under the differ temperature. The high intensity hull structural steel divides its intensity level is according to the minimum yield strength, and every intensity level is divided into A,D,E,F levels which is based on the different impact toughness.
