Stress corrosion cracking (SCC) in boilers and cooling water ...From a historical perspective, over the past century three types of SCC damage in boilers and cooling water systems are considered 'classic' failure mechanisms. In boilers, the 'caustic embrittlement' noted in early, riveted boiler drum designs, has been attributed to have caused numerous catastrophic ruptures in steam locomotives and ...
