Corrosion Resistance of Welds in 21%Cr Ferritic Stainless Steels – Is it Comparable to Type 304L?

Abstract:

Corrosion resistance of gas-tungsten arc welds in two 21% chromium ferritic stainless steels was benchmarked against ferritic type 441 and austenitic type 304L stainless steels. Salt spray, pitting corrosion and ferric chloride tests were carried out for autogenous welds. Also, electron microscopy and glow discharge optical emission spectroscopy examinations were made.The corrosion resistance in 21% chromium ferritic steel welds in chloride environments was seen comparable to those in type 304L, and an improvement was observed when compared to type 441 steel. However, the Mn-Cr-Ti-S sulfide domain may have an undesirable influence on end-grain pitting in ferric chloride test. Weld oxidation results in poor corrosion protection, and artificial mechanical cleaning alone is inadequate for restoring this, and hence pickling is advised.
