Oxygen (O) is a harmful element in steel such as grade P235GH steel material. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

Myanmar's demand for grade p235gh steel material steel products is likely to exceed 3 million tons in 2020 and 5 million tons by 2025, according to seaisi. However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of grade p235gh steel material finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel. In order to reduce its dependence on imports, Myanmar plans to increase its steel production capacity by building and expanding steel mills.

07MnNiMoDR plate is a low welding crack sensitive steel. It is quenched and tempered high strength steel plate for pressure vessel with thickness of 10mm-60 mm. grade p235gh steel material, 07MnNiMoDR plate is widely used in high-end technical fields such as petroleum, chemical industry, power station, boiler, etc. 07MnNiMoDR steel is applied to high-tech products such as reactor, heat exchanger, separator, spherical tank, oil and gas tank, etc.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
