EN steel grade S235JR material,S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).

The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the alloy wear-resistant steel plate is significantly improved.

The data shows that Southeast Asia is the main steel export region of China, and the steel export volume of Asia in 2019 is 37.198 million tons; that of North America and South America is 4.0678 million tons, and that of Europe is 1.1358 million tons. According to the latest epidemic data, South Korea and Japan are the most affected countries in Southeast Asia. However, the growth rate of the number of confirmed cases slowed down significantly, while the situation of the epidemic in Italy, a major European steel export country, was still severe, with the number of confirmed cases exceeding 53000. Therefore, the recovery speed of European market is slower than that of Southeast Asia.
