With the continuous advancement of automobile manufacturing technology, the material selection of automobile body in white structural parts is also being optimized. Among them, steel plate PRG, as a new type of high-performance steel, has shown significant advantages over traditional steel plates in terms of collision safety.
Higher energy absorption capacity
In a collision accident, the body in white structural parts of the automobile need to be able to effectively absorb and disperse the collision energy to protect the safety of the occupants in the car. Steel plate PRG performs particularly well in this regard. Due to its unique material structure and component design, steel plate PRG can deform more reasonably when hit, thereby absorbing more collision energy. This improvement in energy absorption capacity directly reduces the impact of the collision on the occupants in the car and improves collision safety.
Better deformation control ability
In addition to energy absorption capacity, deformation control ability is also an important indicator for evaluating the collision safety of automobile body in white structural parts. When steel plate PRG is hit, its deformation mode is more controllable, which can avoid excessive local deformation or overall collapse. This improvement in deformation control capability enables the body-in-white of the car to maintain better structural integrity during a collision, providing a more stable living space for the occupants in the car.
Better fatigue resistance
During use, the car will experience multiple dynamic processes such as starting, accelerating, and braking, which will produce repeated stress on the body-in-white structural parts. Steel plate PRG has better fatigue resistance and can maintain stable mechanical properties during long-term use, and is not prone to safety hazards such as cracks or fractures. This improvement in fatigue resistance further improves the reliability and durability of the body-in-white of the car.
Stronger corrosion resistance
In harsh use environments, such as humid, saline and alkaline environments, the body-in-white structural parts of the car are susceptible to corrosion. Steel plate PRG has stronger corrosion resistance through special alloy composition design and surface treatment process. This improvement in corrosion resistance not only extends the service life of the body-in-white of the car, but also reduces safety hazards caused by corrosion.
Higher cost performance
Although steel plate PRG may be slightly higher in material cost than traditional steel plates, considering its significant improvement in collision safety and longer service life, steel plate PRG is actually more cost-effective. For automobile manufacturers, the use of steel plate PRG can reduce the repair and compensation costs caused by collision accidents and improve the market competitiveness of products.
Steel plate PRG has significantly improved the safety of automobile collisions compared to traditional steel plates. Its higher energy absorption capacity, better deformation control ability, better fatigue resistance, stronger corrosion resistance and higher cost performance make steel plate PRG one of the preferred materials for automobile body-in-white structural parts.
