Böhler Fox CN 20/25 M-A

Rutile-coated core-wire alloyed stick electrode of type E 20 25 5 Cu N L R / E385-17 (mod.) for highly molybdenum-alloyed austenitic stainless steels such as 1.4539 / UNS S08904. Used in highly corrosive environments encountered in e.g. sulfur and phosphorus production, pulp & paper industry, fl ue gas desulfurization plants; desalination plants, fertilizer production and petrochemical industry; acetic and formic acid production, in pickling plants as well as heat exchangers and power plants using brackish or seawater. Very high pitting
resistance equivalent (PREN  44). Over-alloyed in molybdenum (6.2 wt.-%) to compensate weld metal segregation and improve local corrosion resistance. The fully austenitic weld metal possesses high resistance to pitting and crevice corrosion in chloride containing media. Low C-content makes the weld metal resistant to intergranular corrosion and high Ni-content results in high resistance to stress corrosion cracking. Excellent operating characteristic and easy handling in all positions, except vertical down. The weld metal shows
good slag detachability as well as smooth, fine rippled beads with no residuals.
