Effects of Alloy Content on Impact Toughness in X80 Pipeline Steel [PDF]

open access: yesProceedings of the 2015 2nd International Forum on Electrical Engineering and Automation (IFEEA 2015), 2016
The X80 pipeline steel for the west to east gas transmission project was successful produced, based on the hot strip mills equipment advantage. However, the impact toughness was unstable during the production. In this research, optical microscope, scanning electron microscopy (SEM) and energy dispersive analysis (EDS) test were used to study the ...
