Application of Q390 Steel in Automobile Field

Q390 steel has excellent comprehensive mechanical properties, excellent weldability, cold and hot workability, and corrosion resistance. In addition, Q390 steel also has good low-temperature toughness.

Q390 is a low-alloy high-strength structural steel, which is generally used in the manufacture of automobile bodies. Q390 steel can make the automobile body structure in a high-strength state, and it is not easy to be seriously deformed in the event of a collision. The body of the car is mainly used to protect the driver and form a good aerodynamic environment for the car. The body made of Q390 steel can bring better performance to the car and reflect the personality of the car owner. According to the structural form of the car body, the car body can be divided into two types: non-load-bearing and load-bearing. The load-bearing body does not have a rigid frame, but only strengthens the front, rear and floor. The non-load-bearing body has a rigid frame. The car itself is suspended on the frame, which provides excellent protection for the body, but is stable at high speeds. The high-speed driving stability is not as good as the load-bearing body.
