CCSAH420 steel plate implementation of the national standard: GB711-2011 This specification is used in the production of ocean, coastal and inland navigation areas flying ships, fishing boats and marine engineering structures with a thickness of no more than 150mm steel plate.

GB711-2011 The steel grade and grade specified in this standard are equivalent to the ship regulations of the classification society of nine countries, which is 24 more

grades than the original standardUltra-high strength steel grades - AH420, DH420, EH420, FH420, AH460, DH460, FH460, A5H00, DH500, EH500, FH500, AH550, DH550, EH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690.

GB711-2011 steel grade symbol indicates: such as A, B, D, E are the four grades of steel grade with yield strength of 235MPa, which means that the impact test temperature of the same steel grade is different, which respectively indicates 20 °C, o °C, -20 °C and -40 °C impact;

The three strength levels of 32, 36 and 40 of D, E and F are the four grades of 32kg (315MPa), 36kg (355MPa) and 40kg (390MPa) steel grades with yield strength respectively, indicating that the impact test temperature of the same steel grade is different, which respectively represents 0 °C, -20 °C, -40 °C and -60 °C impact; A, D, E, F 420, 460, 500, 550 four strength levels, respectively on the yield strength of 420MPa, 460MPa, 50OMPa, 550MPa steel grades of the four grades, indicating the same steel grade impact test temperature is different, respectively indicating 0 °C, -20 °C, -40 °C, -60 °C impact.
