KD40 ship plate specification, KRDH40 Korea Classification Society certified ship plate, PCD40 ship

KD40 is a Nippon Bureau of Shipping certified shipboard, KRDH40 is a Korean Bureau of Shipping certified shipboard, and PCD40 is a Russian Bureau of Shipping certified shipboard. The implementation standard GB/T712-2011, delivery state hot rolled or normalized, D for -20 ° impact, this grade is widely used in offshore platforms, decks, shipbuilding, port machinery and so on.

KRDH40 ship plate increases the requirements for the performance of the steel plate thickness direction, that is, the performance in the Z direction, and the additional Z backward is: PCD40-Z35.

KRDH40 belongs to the special steel plate for ships and offshore platforms, and KRDH40 steel plate can be certified by classification society; CCS, DNV, GL, LR, BV, NK, KR, ABS and other nine major classification societies certified

KRDH40 steel plate surface quality

(1) The surface of the steel plate is not allowed to have cracks, bubbles, scars, folds and inclusions and other defects that are harmful to use. There must be no delamination on the sides of the steel plate. If there are the above-mentioned surface defects, it is allowed to be cleaned, and the cleaning depth is calculated from the actual size of the steel plate, and shall not exceed half of the thickness tolerance of the steel plate, and the small thickness of the steel plate shall be ensured. The defect cleaning area should be smooth and free of edges and corners.

(2) Other defects are allowed to exist, and their depth shall not exceed half of the allowable tolerance of the thickness from the actual size of the steel plate, and the thickness of the steel plate at the defect shall not be less than the allowable * small thickness of the steel plate.

(3) Other additional requirements: According to the requirements of the buyer, the additional technical requirements for chromium-molybdenum steel plates for hydrogen use can be specified by agreement between the supplier and the buyer and the contract.

Under normal circumstances, a certain steel plate used is the standard of the Chinese classification society, so all the steel plates need to use the standard of the same national classification society under the standard. Ship plate refers to the hot-rolled steel plate produced according to the requirements of the construction code of the classification society for the manufacture of ship hull structure.
