254 SMO®


254 SMO is an austenitic 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 technically adequate and much less costly substitute for nickel-based alloys and titanium. 254 SMO is readily fabricated and welded.
