1.Introduction.High strength structural steel (HSSS) usually refers to the steels with a nominal yield stress not less than 460 MPa .HSSS can sometimes offer economic benefits compared to more conventional mild structural steel,and has been applied to several landmark buildings and major projects .Although Q460 (the Chinese Grade of steel with nominal yield strength of 460 MPa ) to High Temperature Mechanical Properties of High Strength Jul 20,2018·This paper reports the results of an experimental study on high temperature mechanical properties of high strength structural steel produced in accordance with Chinese materials standards.Steady-state tensile coupon tests were carried out on specimens made of China grade steels of Q550,Q690 and Q890.Nine elevated temperature levels up to 800°C were considered.IOP Conference Series Materials Science andThe tensile curves of Q690 steel plate after different heat treatment are shown in Fig.2.Figure 2.Stress-strain curves of Q690 steel plates under different heat-treatment process.Compared with the stretching curves in Fig.2,the strength of the steel plate treated by Q-P-T heat treatment process is higher than the original steel plate.
