Thermoformed steel plate
The hot-formed steel plate technology refers to the steel plate after being heated at a high temperature of 950 ° C, and then rapidly cooled to increase the strength of the steel plate. The yield is up to 1000 Mpa, and the pressure per square centimeter can withstand more than 10 tons. The material is used on the body, and the bearing capacity is increased by 30% under the condition that the weight of the vehicle is hardly changed, so that the rigidity of the car reaches a new level, and the five-star standard is reached in the European NCAP crash test.

The strength of a body depends on the design of the body and the strength of the steel plate. Therefore, the strength of the steel plate in the important protection part of the body is very important. The thermoformed steel plate is undoubtedly the leader in all kinds of high-strength plates. [1] 

Advantage editing
Extremely high material strength and ductility. The tensile strength of general high-strength steel sheets is about 400-450 MPa, while the tensile strength of hot-formed steels before heating has reached 500-800 MPa, and after heating forming, it is increased to 1300-1600 MPa, which is 3-4 times that of ordinary steel. Its hardness is second only to ceramics, but it also has the toughness of steel. Therefore, the body made of thermoformed steel plate greatly improves the collision resistance and overall safety of the vehicle body, and plays a good role in protecting the inside of the vehicle during the collision.
Effectively reduce the weight of the vehicle and save energy. Due to the extremely high material strength of thermoformed steel sheets, it is possible to replace a number of common steel sheet parts with a hot formed part during design. For example, the B-pillar in the middle of the front and rear doors of the Sagitar model eliminates the need for reinforcing beams due to the use of thermoformed steel sheets. By reducing the strength of the five parts, the weight loss is about 4.5 kg, which naturally reduces the fuel consumption of the car. The cost of ownership of the owner also plays a supporting role. The weight of the Magotan is reduced by the use of thermoformed steel sheets and is close to 10 kg.
Thermoformed steel sheets have excellent material forming accuracy, eliminating the effects of material springback and enabling complex shapes. Due to the special properties of the thermoformed steel sheet and the forming after heating, it is possible to complete a complicated shape in which a common cold stamping forming process requires a plurality of processes in one process. The advantage of the one-time forming process is that it can ensure that the inner fiber flow direction of the steel plate does not have to be impacted by the secondary force during the processing, ensuring that the steel plate maintains the best strength and toughness, and that the parts are quickly cooled after forming, after the parts are formed. The amount of rebound is small, which greatly improves the material forming accuracy, better guarantees the dimensional accuracy of the parts, and lays a good foundation for the next body welding.
The raw materials for thermoformed steel sheets are patented by European steel giants Dessen-Krupp and Arcelor-Mittal. All steel plates are imported from Europe. At present, China's production lines are gradually increasing, and there will be more than 10 at the end of 2013. The production line is put into production.
Feature editing

Ultra-high strength and high strength body materials for high mechanical safety. The thermoformed steel plate is mainly applied to the front and rear bumper frames and key parts such as the A-pillar and the B-pillar. When the impact occurs, especially in the front and side impact, the cockpit deformation can be effectively reduced, and the safety of the driver and passenger can be protected. .
