High-alloy austenitic stainless steels prove worth in sour gas fields ///

Standard stainless steels used in hydrocarbon production offer a number of advantages—such as corrosion resistance, economy and safety—compared to traditional low-alloyed materials. Nevertheless, these standard grades are proving insufficient in deeper, more hostile environments that contain corrosive elements, such as carbon dioxide (CO2), hydrogen sulfide (H2S) and chlorides.
