STRESS CORROSION CRACKING OF STAINLESS ALLOYS IN OXYGENATED CAUSTIC ENVIRONMENTS

摘要

The temperatures required to produce fully oxidized white liquor are capable of causing stress corrosion cracking (SCC) on the 300 series of austenitic stainless steels (304L/316L). This report outlines the likely mechanisms for SCC of 316L/304L in white liquor oxidizer systems, and suggests ways in which SCC can be prevented. Case histories are given and alternative alloys are suggested.
