Abstract:  
Power producers spend nearly $10 billion a year fighting corrosion, and that is only covering the United States. Stress Corrosion Cracking (SCC) can cause sudden, catastrophic and costly failures. Power facilities attempt to prevent SCC by using materials that are generally thought of as SCC resistant, like austenitic stainless steels and nickelbased alloys. Despite the general corrosion resistance, even some conditions of austenitic stainless steels and Ni-based alloys are susceptible to SCC. High-strength ferritic alloys can be susceptible to sulfide stress cracking. Many alloys are subject to other types of environmentally assisted cracking under the right conditions, namely a corrosive environment and tensile stress above a certain threshold.
