CCSDH500 Offshore engineering structural steel plate, CCS-DH500 ship plate specification, DH500 stee

CCSDH500 is China Classification Society certified offshore engineering structural steel plate, divided into A, D, E, F four quality grades, namely AH550, DH550, EH550, FH550, H is high-strength building materials, 550 is the lower yield strength.

Z-direction steel: also known as "lamellar tearing resistant steel", that is, the usual Z-direction performance. In the steel structure with welded connection, when the thickness of the steel plate is not less than 40 mm and the tensile force along the thickness of the plate is subjected, in order to avoid lamellar tearing during welding, it is necessary to use lamellar tear-resistant steel (usually referred to as "Z-direction steel"). The thick plate has the problem of lamellar tearing, so the Z-direction performance test should be proposed.

The steel plate with Z-direction requirements is added to the suffix Z25 and Z35, and the use is ultra-high-strength structural steel
