Cromarod 385 is a rutile flux coated electrode designed for welding the fully austenitic stainless steels
of the 20%Cr / 25%Ni / 4.5%Mo / Cu type, used for their very high resistance to corrosion in severe,
non-oxidising environments e.g. sulphuric acid. The low carbon, high alloy content of Cromarod 385
weld metal gives excellent resistance to intergranular corrosion and stress corrosion cracking,
combined with superior resistance to crevice and pitting corrosion. Use no preheat, avoid high
heat-input and maintain an interpass temperature of maximum 150 °C.
For very severe corrosion environments a special variant of this electrode, with a Mo content of 6%, is
available to order.

Chemical composition, wt.%
Very good resistance to general and intergranular
corrosion in non-oxidising acid environments e.g.
sulphuric (up to 90%), phosphoric and organic
acids. Good resistance to stress corrosion in
chloride bearing environments.
