Ship steel has strict requirements for steel quality, and its strength, toughness and appearance quality are higher than ordinary steel standards.
Ship steel, such as 921A. Generally speaking, they are steel plates with large layout and few small specifications. Because the larger the area of 921A (10CrNi3MoV) steel plate is, the less the number of welds will be, which can shorten the construction period and improve the overall quality of the deck.
Don’t ask why you can’t cut the board and sell it.
