For the selection of 150mm GL-FH 40 hull structural steel, automobile steel plate products and manufacturers, we should not only check the material processing quality, but also check how the actual installation and use effect are. The comfort, bearing capacity and other indicators of the auto made of the automobile steel plates should also be considered. In addition, in choosing 150mm GL-FH 40 hull structural steel, automobile steel plate manufacturers and products, it is better to find a few more companies to compare, and conclude to choose a more suitable automobile steel plate manufacturer.
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the 150mm GL-FH 40 hull structural steel plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
What is the difference between Q345B steel and Q345A steel? 150mm GL-FH 40 hull structural steel, 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.
