CCSAH620 is a China Classification Society certified high-strength ship plate steel, marine steel according to the use of classification for: general strength ships and structural steel for marine engineering, high strength ships and structural steel for marine engineering and ultra-high strength ships and structural steel for marine engineering three categories. Steel grade symbols: such as A, B, D, E for the yield strength of 235MPa steel grade of the four grades, indicating that the same steel grade impact test temperature is different, respectively, 20 ℃, 0 ℃, -20 ℃, -40 ℃ impact.
CCSAH620 steel plate implementation standard:GB 712-2011 ship and marine engineering structural steel;
