Features
duplex
superb corrosion resistance in chloride containing media
weldable (except gas welding)
machining properties comparable with material 1.4462
polishable, but modified appearance of the polishing result is to be expected due to the two-phase structure
good resistance against surface-wide corrosion
comparable to common austenite grades, improved resistance against pitting and crevice corrosion
