CCSFH460 is an ultra-high-strength ship steel plate certified by China Classification Society. It is a structural steel for ships and ocean engineering. F is the quality grade, H is a high-strength building material, and 460 is the lower yield strength. Steel plates with Z-direction requirements have the suffix Z25 or Z35 added, and are used as ultra-high-strength structural steel for ships and ocean engineering.
CCSFH460 heat treatment status: The steel plate is in the quenching and tempering, normalizing, thermomechanical rolling + tempering status, and the status can also be specified according to technical requirements.

CCSFH460 steel plate implementation standard: GB711-2011
This standard is used for manufacturing steel plates with a thickness of no more than 150mm for ships, fishing boats and marine engineering structures in ocean, coastal and inland navigation areas.
Z-direction steel: also known as "lamellar tearing resistant steel", which is what is usually called Z-direction performance. In steel structures connected by welding, when the thickness of the steel plate is not less than 40 mm and it bears tensile force along the thickness direction of the plate, in order to avoid lamellar tearing during welding, it is necessary to use steel that resists lamellar tearing (usually referred to as "Z"). "To Steel"). Thick plates have lamellar tearing problems, so Z-direction performance testing is required.
