Development of 700 MPa Grade Ultra-high Strength Heavy Duty Automobile Carriage Strip

Microstructure and properties of 700MPa grade HSLA steel during high temperature deformation

“…It is widely used in many important steel structure areas such as hydraulic support, module vehicles, bridges and nuclear power reactor construction [1][2][3]. With the rapid development of heavy industry and the corresponding equipments, the 700 MPa grade HSLA steel have gradually been applied in various fields [4]. The hot deformation process is an indispensable technology for practical application of HSLA steels, the deformation characteristics of HSLA steels have drawn the attention of many researchers for many years.…”
