CCSFH420 steel plate size, shape, weight and allowable deviation: the size, shape, weight and allowable deviation of the steel plate shall comply with the provisions of GB709.

FH420 steel plate thickness deviation: N, A, B, C Class

N deviation: positive deviation Negative deviation equal

Class A deviation: Negative deviation

determined by nominal thickness Class B deviation: fixed negative deviation of

Class C deviation: the fixed negative deviation is 0, and the positive deviation

is determined according to the nominal thicknessGB712-2011 Structural Steel for Ships and Offshore Engineering Structural Steel Code The trademarks are: A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, AH420, DH420, EH420, AH460, DH460, EH460, FH460, AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690

CCSFH420 steel plate can be produced according to the needs of users in different national specifications of marine steel, such as the United States, Norway, Japan, Germany, France, etc., and its classification society certification is as follows:

CCS USA ABS GERMANY GL FRANCE BV NORWAY DNV JAPAN NK UK LR Italy RINA South Korea KR (Norway DNV merged with Germany into: VL, nine major classification societies certified.

According to the technical maturity and physical quality stability of the steel plate for high-strength welded structures developed in China in recent years, the 550 steel grade and below are supported by production performance data; Although there is no production of marine steel for the time being, 620 and 690 steel grades have a large number of production performance in other industries and uses, and the steel mill has the technology and equipment capabilities for research and development and production, and the equivalent use of the specifications of various classification societies is also one of the bases.

The inclusion of high-strength steel grades in this standard is the need for production and use, the need for technological progress and economic development, and the embodiment of the rapid development of technical equipment in the metallurgical industry in recent years
