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.
