This kind of steel A514 grade B structural steel material is generally used in the quenched and tempered state, and can also be used in the normalized state, and is suitable for manufacturing parts that work under higher stress and wear conditions. When the diameter of the workpiece is less than 60mm, the performance of 45mn2 structural steel is equivalent to that of 40Cr steel. 45mn2 structural steel is used in parts under higher stress and wear conditions, such as universal joint shafts, axles, connecting rod covers, friction discs, worms, gears, gear shafts and other quenched and tempered or normalized parts.
We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the A514 grade B structural steel material project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It A514 grade B structural steel material is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
It is a modern high-tech professional enterprise integrating scientific research, A514 grade B structural steel material production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A514 grade B structural steel material process technology development, technology transfer and related technical consulting and technical services.
