This is a fully austenitic alloy with a typical ferrite content of 0.5 FN maximum. One of the primary uses of this filler metal is for the joining of similar and dissimilar cryogenic steels for applications down to –269°C. This filler metal also exhibits good corrosion resistance in acids and seawater, and is particularly suited for corrosion conditions found in urea synthesis plants. The high Mn-content of the alloy helps to stabilize the austenitic microstructure and aids in hot cracking resistance.
