Analyze the availability of S235 steel in the field of new energy vehicles

1. Characteristics of S235 steel
Good load-bearing capacity: S235JR is suitable for general building structures and bridges. It has good load-bearing capacity and anti-seismic performance, and can effectively improve the structural safety and stability of buildings. This feature may be applied to the frame structure of new energy vehicles. The frame needs to bear the weight of the vehicle body and various stresses during driving. The load-bearing capacity of S235 steel can meet some needs.
Processability: The good processability of S235 steel helps to manufacture components of various shapes and structures. In the manufacturing of new energy vehicles, if there are some non-critical structural parts that require certain shapes, the processability of S235 steel can play a role.

2. New energy vehicle structure and demand analysis
Body frame: In addition to meeting basic load-bearing requirements, the body frame of new energy vehicles also needs to consider lightweighting. If the strength requirements are not extremely high and the weight limit is relatively loose, S235 steel will be used. For example, some urban commuter new energy vehicles have relatively mild driving speeds and working conditions. S235 steel can be used in the body frames of these vehicles.
Parts support structure: There are many parts inside new energy vehicles that require support structures to fix and position. For some support structures that do not involve high-precision requirements such as power systems and battery management systems, S235 steel will also be selected if it can meet basic mechanical properties, corrosion resistance and other requirements.

However, due to the increasing requirements of new energy vehicles in pursuit of lightweight, high performance, and high safety, and the tendency to use new materials with high strength, lightweight, and special properties (such as good conductivity, electromagnetic compatibility, etc.) in many key parts, the application of S235 steel in new energy vehicles may be relatively limited.
