Description:

Cromarod 383 is a rutile flux coated electrode specially designed for high alloyed fully austenitic

stainless steels of similar composition e.g. Sandvik Sanicro 28. It deposits a 27%Cr / 31%Ni /

3.5%Mo / 1%Cu weld metal with exceptionally good corrosion resistance in non-oxidising acid

environments, e.g. sulphuric and phosphoric. With a PRE of approximately 40, the electrode has

even higher resistance to pitting corrosion than Cromarod 385.
