Ship Plates for Sale

Steel for hull structure refers to the steel used for manufacturing hull structure produced according to the requirements of classification society construction specifications. Hull structural steel is very important to shipbuilding industry. The general strength hull structural steel is divided by the hull structural steel according to its small yield point strength, and the corresponding high-strength hull structural steel and dance steel plate. Shipbuilding steel generally refers to the steel high-strength ship plate for hull structure. It refers to the steel used to manufacture hull structure produced according to the requirements of classification society construction specifications. It is often used for steel ordering, production scheduling and sales. A ship includes ship plate, section steel, etc.

Steel for hull structure refers to the steel used for manufacturing hull structure produced according to the requirements of classification society construction specifications. Hull structural steel is very important to shipbuilding industry. It also requires economy and reliability. Shipbuilding materials should have low cost, many varieties, good quality and ensure a large supply. To meet these requirements, we must be based on China, and domestic materials should have good supply economy. If the thickness of ship plate is upgraded, the quotation of ship steel plate can be 0.5mm, and the angle steel can be unequal in thickness. Only in this way can we ensure sufficient supply of goods and meet the needs of China's shipbuilding industry.

What are the characteristics of marine steel plate: due to the poor working environment of the ship, the hull shell is subject to chemical corrosion, electrochemical corrosion, marine organisms and microorganisms; The hull bears large wind wave impact and alternating load; Ship shape makes its processing method complex, so it has strict requirements for hull structure steel. First of all, good toughness is the key requirement. In addition, ship plate dealers with high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality are required.

Hull steel is a professional carbon steel used for the construction and repair of ship shells and their auxiliary structures. Professional carbon steel used for building and repairing ship shells and their auxiliary structures. The performance of this kind of steel determines the hull structure design and construction technology. Therefore, there are strict requirements for the chemical composition, mechanical properties, process properties and quality of steel in order to ensure the shipbuilding quality. Marine steel is required to have certain strength, toughness and, certain low temperature and corrosion resistance, and good welding performance.

Hull steel has strict requirements on chemical composition, mechanical properties, process properties and quality of steel: carbon hull steel should have sufficient strength and good plasticity, toughness and fatigue strength. Yield strength is the basic technical basis for calculating hull strength and determining hull structure size. Carbon hull steel with different yield strength should be selected for different hull construction. Only when the material has good plasticity can it undergo cold and hot processing in the processing process and avoid damage due to local stress during navigation.

Hull steel should have enough toughness and fatigue strength. Toughness is the ability to resist brittle failure. Due to the different stress state, loading speed and temperature after machining, the tendency of brittle state of hull steel is also different, and brittle fracture is easy to occur. Therefore, good toughness, especially low-temperature toughness, is required to ensure the safety of ocean navigation. Fatigue performance is to ensure that the ship will not produce low cycle fatigue under various alternating loads, so as to improve the service life of the ship.
