Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel CCS DH32 container vessels steel products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.
20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the CCS DH32 container vessels steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
