Growth of S420ML steel plates exported to the Middle East

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important S420ML steel plates heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

A709Gr.36 steel plate is used in construction steel structures, construction machinery and other steel structures, and has been exported to South Korea, Singapore, Malaysia, Dubai, Nigeria and other countries. The S420ML steel plates) cumulative export volume has reached more than 10,000 tons. Construction steel structure, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for construction and engineering machinery parts that require good weldability and toughness.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of S420ML steel plates, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.

Phosphorus is a very harmful element in S420ML steel plates steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of S420ML steel plates 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.

What is the difference between Q345B steel and Q345A steel? S420ML steel plates, 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.
