With the advent of hydrocracking and high pressure, high severity desulfurization of gas oils and heavier materials, a great number of materials problems were anticipated. Field experience in lower pressure processes had shown that high rates of corrosion could occur in hydrogenhydrogen sulfide environments above 500°F. As a result, large volumes of laboratory data were gathered, indicating that for reactor vessels, heaters, feed-effluent exchangers and hot transfer lines, austenitic stainless steels and ferritic stainless steels would be required. In fact, early laboratory data indicated relatively high corrosion rates could be anticipated on even the stainless steels.
