A. 254SOM UNS S31254 UNS J93254 EN 1.4547 F44 BMLCuN ACI CK3MCuN Overview
General Characteristics
Outokumpu 254 SMO is an austenitic stainless steel designed for maximum resistance to pitting and crevice
corrosion. With high levels of chromium,molybdenum, and nitrogen, 254 SMO is especially suited for high-chloride environments such as brackish water, seawater, pulp mill bleach plants, and other high-chloride process streams.
In new construction, 254 SMO has been found in many cases to be a technically adequate and much less
costly substitute for nickelbase alloys and titanium. 254 SMO is substantially stronger than the common
austenitic grades, and it is also characterized by high ductility and impact strength. 254 SMO is readily
fabricated and welded.
Design Features
High resistance to pitting and crevice corrosion
Very high resistance to chloride stress corrosion cracking
50% stronger than 300-series austenitic stainless steels
Excellent impact toughness
Excellent workability and weldability
