Stress corrosion cracking of boiler components is a well known phenomenon and is easily controlled by the use of proper water chemistry during boiler operation. Occasionally water chemistry can go astray and stress corrosion cracking can occur. This paper describes a steam drum cracking incident which transpired in a coal-fired boiler at the Savannah River Plant, Aiken, South Carolina. Metallurgical analysis, in-situ testing results, and water chemistry analyses are discussed in this paper.
