Bohler CN 20/25 M-IG (SI) description: GMAW solid wire for corrosion resistant 4-5 % Mo alloyed CrNi-steels like 1.4539 / 904L. Very high pitting resistant equivalent (PREN  45) – pitting potential (%Cr + 3.3 x %Mo + 30 x %N). Due to the high Mo content (6.2 %) in comparison to W.-No. 1.4539 respectively UNS N08904, the high segregation rate of high Mo-alloyed CrNi-weld metal can be compensated. The fully austenitic weld metal possess a marked resistance towards pitting and crevice corrosion in chloride containing media. Highly resistant against sulphur-, phosphorus-, acetic- and formic acid, as well as sea-and brackish water.
