In the past 20 years, numerous investigators have examined the relationships between resistance to sulfide stress cracking (SSC) and the chemical and mechanical properties of steel. Hardness has become an accepted quality control tool for evaluating C-90 grade casing for sour gas service. 1  The 4100 series steels used to produce C-90 grade casing were selected, however, by an empirical process. Because of their success in withstanding this environment, and because of the economic factors involved in finding an immediate solution to the problem of producing these wells, the primary emphasis has been on materials for even higher strength service rather than on the mechanisms involved in the sulfide stress cracking of the 4100 series steel..
