Generally, in the process of selecting S355ML VS S355J2, automobile steel plate manufacturers, the most important thing is to look at the appearance and thickness of automobile steel plates produced by manufacturers. Generally, the appearance of good S355ML VS S355J2, automobile steel products is relatively fine, there are no obvious defects on the surface of automobile steel plate, and the thickness of automobile steel plate is within the specified range value. These are very important factors to measure the production capacity of the manufacturer and the quality of automobile steel plate products.
The difference between S355ML VS S355J2, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
The fake and inferior S355ML VS S355J2, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
Chemical composition differences between the S355ML VS S355J2, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):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。
