sp.info Hydrogen Effects on X80 Steel Mechanical Properties ...properties of X80 pipeline steel were investigated by slow strain rate test (SSRT), Charpy impact test, and scanning electron microscopy (SEM) in this thesis. The results show that both the ultimate tensile strength and elongation to failure of X80 steel were deteriorated significantlysp.info Effects of shot peening on tensile properties and fatigue ...Meanwhile, the fatigue properties of X80 steels were severely impaired by the synergistic action of the stress concentration and the low-pressure hydrogen gas. This work aims to inhibiting hydrogen-assisted degradation of X80 steels which is used to transport coal gas by SP treatment.sp.info API 5L X80 steel ,API 5L X80 steel Test - Steel Exporter ...
