SSC/SCC
Stress corrosion cracking (SCC) is the unexpected failure of normally ductile metals subjected to a tensile stress in a corrosive environment. SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to certain corrosive environments. Sulfide stress cracking (SSC) is a form of hydrogen embrittlement which is a cathodic cracking mechanism. Susceptible alloys, especially steels, react with hydrogen sulfide, forming metal sulfides and atomic hydrogen, which causes SSC. This section provides access to reports that present test results and evaluate the resistance to SSC/SCC of various materials when exposed to different corrosive environments.
