Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel GL-A36 Ro-Ro ship steel plate can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.
Phosphorus is a very harmful element in GL-A36 Ro-Ro ship steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of GL-A36 Ro-Ro ship steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
The rise and fall of GL-A36 Ro-Ro ship steel plate, steel pipe price will be affected by many factors, such as market demand. If the construction of real estate industry, basic road construction and so on industries is booming, the sales volume of steel pipes will be very good, and the market supply will gradually increase. The market demand has a very important guiding significance for GL-A36 Ro-Ro ship steel plate, steel pipe manufacturers, dealers and agents in many regions.
In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the GL-A36 Ro-Ro ship steel plate steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
