STATUS REVIEW OF ALLOY 800 PAPER No. 7
TITLE OF PAPER AUTHOR ORGANIZATION
One of the contaminants most likely to occur in boiler waters is chloride and this could arise, for instance, from a condenser tube failure especially in a coastal plant. I would, therefore, like to make a comment on the resistance of Alloy 800 to chloride stress corrosion cracking with reference to other environmental factors and in relation to other candidate alloys for boiler tubes.
As a broad generalization, austenitic stainless steels at the 15-20% chromium level are susceptible to chloride stress corrosion cracking, but the degree of susceptibility varies with a number of factors of which the most important environmental ones are chloride concentration, pH, temperature and oxygen
