ER385

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.
