Environmentally assisted cracking (EAC) is a general term used to describe a number of failure modes in which the corrosivity of the environment is a causative factor, e.g. stress corrosion cracking, corrosion fatigue, hydrogen embrittlement, etc. This paper discusses the wide range of problems and failures due to EAC in the Pulp and Paper Industry, using a number of case histories.
Keywords: corrosion, fatigue, digesters, paper machines, recovery boilers, stress corrosion cracking.
