摘要
Abstract
The effect of hot rolling/stretch reducing+quenching and tempering on microstructure and mechanical properties of the C-Mn steel weld was investigated by Gleeble 1500 thermal simulation test and HFW pipe hot stretch reducing test,and the accelerated corrosion method using constant potential anodic polarization was adopted to study the influence on grooving corrosion(GC) sensitivity of C-Mn steel weld of hot stretch reducing+quenching and tempering. The result showed that the micro-structure and the grain state of the weld are the same as those of base metal after HFW pipe hot stretch reducing and hot treatment,moreover,the mechanical properties and the grooving corrosion resistance are improved to the lever of base metal basically and achieve the weld optimization or the seamless goal of welded pipe.关键词
