What is shipbuilding steel plate?
The strength grade of hull plates is divided into general strength structural steel and high strength structural steel according to their lowest yield point. Ship plates refer to hot-rolled steel plates used to manufacture ship hull structures produced in accordance with the requirements of classification society construction specifications. General strength structural steel stipulated by China Classification Society is divided into four quality grades A, B, D, and E (i.e., CCSA, CCSB, CCSD, CCSE); high-strength structural steel stipulated by China Classification Society is divided into three quality grades. : Strength level, four quality levels.
Ship plates are divided into strength grades according to their minimum yield point: ordinary strength structural steel and high-strength structural steel. Ship plates refer to hot-rolled steel plates used to manufacture ship hull structures produced in accordance with the requirements of classification society construction specifications.
Ship plate is a type of steel plate used in shipbuilding, including thin plates and medium-thick plates. Chinese classification specifications divide steel plates into four quality grades ABDE, namely CCSA, CCSB, CCSD, and CCSE. There are many main materials for ship plates, such as stainless steel, galvanized materials, iron ship plates, wooden ship plates, etc. Each material is used in different places. Generally, large-scale cargo ships at sea use stainless steel plates. Otherwise, if the ship plates rust, it will not only pollute the sea water, but also have an impact on the ship itself. Many tourist attractions use wooden boats just for sightseeing and are more environmentally friendly.
Many people easily confuse ship plates with ordinary steel plates. So what are the differences and comparisons between ship plates and ordinary ship plates? First, the ship plates must be thicker and more precise than ordinary steel plates. Otherwise, it will break due to the impact of sea water during operation, which will bring life danger to the people on board. Secondly, the difference between ship plates and ordinary steel plates is that they are more corrosion-resistant. Ships are immersed in seawater for a long time. If they do not have good corrosion resistance, the ship plates will easily rust and the weight of the hull will also be reduced. It will become larger, and it will also bring pollution to the seawater and cause ecological damage. Third, it has better ability to resist wind and waves. We often encounter strong winds and waves in the ocean. If the ship board itself has excellent performance and is not protruding, it will be easily damaged by strong winds and waves. Fourth, the service life is longer. Due to these excellent properties of ship boards, ship boards can be used for a long time. Some old boats can be dismantled and recycled. Fifth, the price is higher than ordinary steel plates. The thickness and strength are higher, and the processing steps are more complicated, so the price increases.
