QStE340TM automobile structural steel is high yield strength automotive steel for cold forming. 340 in QStE340TM refers to its lower yield strength limit 340 MPa.
The rapid development of automobile industry plays an important role in the development of national economy and society. However, due to the impact of energy shortage, environmental pollution and other issues, the contradiction of industry development is increasingly prominent. Looking forward to the future, the development of automobile industry can only be sustainable if it is built on the premise of nature, ecology, energy conservation and safety. Under the background, the application of automobile lightweight and QStE340TM automobile structural steel etc. high strength steel has become an important development direction. According to statistics, the application of QStE340TM automobile structural steel and so on high-strength steel is expanding. The application of QStE340TM automobile structural steel and so on high-strength steel for body frame of some automobile models has reached 90%.
QStE340TM automobile structural steel has good strength and cold forming properties. QStE340TM automobile structural steel is widely used in automobile frame, girder and other automobile structural parts with high requirements for forming performance and strength.
