According to the market forecast released by Eurofer on August 5, the output of all A514 Gr P QT steel plate steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the A514 Gr P QT steel plate steel consumption intensity in the construction industry significantly less than other industries.
The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality A514 Gr P QT steel plate products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.
The corrosion resistance of stainless steel depends on the alloy elements contained in the steel. The chemical composition of A514 Gr P QT steel plate, stainless steel and acid resistant steel is different. The former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The better stainless steel also contains nickel. Adding molybdenum can further improve the atmospheric corrosion resistance of stainless steel, especially the corrosion resistance of chloride containing atmosphere.
What is the difference between Q345B steel and Q345A steel? A514 Gr P QT steel plate, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe A514 Gr P QT steel plate for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.
