CCSAH620 High Strength Marine Plate Steel Plate, CCS-AH620 Marine Structural Steel Plate, AH620 Stee

CCSAH620 High Strength Marine Plate Steel Plate, CCS-AH620 Marine Structural Steel Plate, AH620 Stee

CCSAH620 is China Classification Society certified high-strength ship plate steel plate, marine steel is classified according to use: general strength ship and marine engineering structural steel, high-strength ship and marine engineering structural steel and ultra-high strength ship and marine engineering structural steel. Steel grade symbol representation: such as A, B, D, E are the four grades of steel grade with yield strength of 235MPa, which indicate that the impact test temperature of the same steel grade is different, which respectively indicates 20 °C, 0 °C, -20 °C and -40 °C impact.

CCSAH620 steel plate implementation standard: GB 712-2011 structural steel

for ships and marine engineeringThe grades specified in GB712-2011 structural steel standard for ships and offshore engineering are: A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, AH420, DH420, EH420, FH420, AH460, DH460, EH460, FH460, AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690

general strength ship plate: A, B, D, E. High-strength shipboard: AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH36 and ultra-high-strength shipboard DH460, EH460, EH550, EH690, etc. Thickness: 3-80mm, width 1500-4000mm, length 4000-19000mm. Certified by the world's nine major classification societies (CCS, ABS, VL, LR, BV, NK, KR, RINA, RS).

The provisions of this standard grade: equivalent to the provisions of the CCS specification of China Classification Society. The grade of steel is composed of two parts: the English letter representing the quality level and the yield strength value.

For example: D36. Among them: D - the quality level is D
