E2553-16 is an electrode which is designed
to run on a direct current with reverse polarity
as well as alternating current. This electrode
is used for the welding of Ferralium 255
and duplex stainless steels which contain
approximately 25% chromium. The weld
metal deposit of these electrodes has a
“duplex” microstructure which consists of
an austenite-ferrite matrix. E2553-16 weld
deposit combines an increased tensile
strength with an improved resistance to
pitting, corrosive attack and to stress
corrosion cracking.
