A Comparative Study of Hydrogen-Induced Cracking Resistances of API 5L B and X52MS Carbon Steels

Figure 6

SEM and EDS analyses of corrosion products in the API 5L X52MS steel. This steel exposed to 177-A solution: (a) 200x, (b) 3000x, and (c) EDS. This one exposed to 177-B solution: (d) 200x, (e) 3000x, and (f) EDS. This one exposed to 284-B solution: (g) 200x, (h) 3000x, and (i) EDS.
