The weight of the ship plate can be set according to the weight required by the ship, so that neither the weight of the ship nor the speed of operation will be affected. The price of SA573 Gr70 carbon steel, medium and thick ship plates is determined according to the thickness and quality, which can be combined with the cost of shipbuilding to calculate the price, and then make a choice, so that it will not affect the cost of shipbuilding.
