Description:
Cromamig 385 is intended for welding the 20% Cr / 25% Ni / 4.5% Mo / Cu fully austenitic stainless
steels, used for their very high resistance to corrosion in severe, non-oxidising environments e.g.
sulphuric acid. The low carbon, high alloy content of the weld metal gives excellent resistance to
intergranular corrosion and stress corrosion cracking, combined with superior resistance to crevice
and pitting corrosion compared to standard 304L and 316L materials.
Welding current:
DC+

Corrosion resistance
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
cracking and crevice and pitting corrosion in
chloride bearing environments.
Scaling temperature:
Approx. 1000°C in air.
