The difference between marine steel plates and ordinary carbon steel plates
Steel plates for ship hull structure are abbreviated as ship plates. Due to the harsh working environment of ships, the outer shell of the ship is subject to chemical corrosion, electrochemical corrosion, and corrosion by marine microorganisms; The ship is subjected to significant wind and wave impacts and alternating loads; Due to the complex processing methods caused by the shape of ships, strict requirements are placed on the use of steel for ship structures. Firstly, good toughness is the most critical requirement. In addition, it requires high strength, good corrosion resistance, welding performance, processing and forming performance, and surface quality. To ensure quality and sufficient toughness, it is required that the chemical composition of Mn/C be above 2.5, and there are strict requirements for carbon equivalent, which should be produced by steel mills recognized by the ship inspection department.
Do you know the difference between ship steel plates and ordinary carbon steel plates?
Different materials. Ship steel plates are usually made of low alloy high-strength steel, which has a certain strength and toughness and can meet the special requirements of ship structures and marine environments. Ordinary steel plates may be mainly composed of elements such as carbon and iron, with relatively simple composition, wide applications, and relatively cheap prices.
The strength and corrosion resistance are different. Marine steel plates have high strength and durability, and many of them also have excellent low-temperature toughness and high corrosion resistance. This is because marine steel plates usually contain elements that can improve toughness and corrosion resistance, such as nickel, chromium, molybdenum, etc. In contrast, ordinary steel plates have poorer performance in these aspects.
The processing technology is different. The processing of ship steel plates usually includes a series of processes such as hot rolling, sandblasting, and surface treatment, and may require different degrees of plasticity processing to meet the requirements of different parts of the ship. In contrast, the processing technology of ordinary steel plates is relatively simple.
Different uses. Marine steel plates are mainly used in the fields of ship construction and marine engineering, while ordinary steel plates are widely used in the manufacturing of building panels, automotive components, heavy machinery, and other fields.
Overall, marine steel plates are a special type of steel that differs significantly from ordinary steel in terms of material composition, manufacturing process, performance, etc. These differences are mainly aimed at adapting to the special requirements and harsh environments of the shipbuilding and marine engineering fields.
