corrosion of C-steels and austenitic stainless steels is well
documented, there are little or no published data relating to
its behavior on DSSs or other high strength alloys.
To address the above mentioned issues, TWI undertook
a Joint Industry Programme (Ref 1) which comprised
a detailed evaluation of the performance of TSA-coated,
22% Cr DSS welds subjected to pitting corrosion, external
chloride stress corrosion cracking (SCC), and hydrogeninduced
stress cracking (HISC). TSA corrosion rate data
were produced at ambient and elevated temperatures
using two electrochemical techniques. The effects of
sealant selection on TSA coating behavior were characterized,
and conclusions were drawn from the above data.
