ASTM A283 ms steel sheet,Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, based on a high starting point and high technology, the company has vigorously developed various steel products ASTM A283 ms steel sheet and deep-processed parts, steel structures, precision castings, seamless pipes.
The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel, ASTM A283 ms steel sheet are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.
Grades , Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance C, D, E grade steel has good low temperature toughness Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts,ASTM A283 ms steel sheet.
ASTM A283 ms steel sheet,After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to full material Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality In early 2008, the company established the Ministry of foreign trade, and our steel plate products are now exported to the South Asia, the Middle East, Europe and the United States,ASTM A283 ms steel sheet.
Chemical composition differences between the Q345 steel grades (Q345A / 345B / 345C / 345D / 345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
