DESCRIPTION
254SMO is an austenitic stainless steel designed for maximum resistance to pitting and
crevice corrosion. With high levels of chromium, molybdenum, and nitrogen, 254SMO is
especially suited for high chloride environments such as brackish water, seawater,
pulp mill bleach plants and other high chloride process streams. 254SMO offers chloride
resistance superior to that of Alloy 904L, Alloy 20, Alloy 825 and Alloy G. 254SMO is
compatible with the common austenitic stainless steels. It is often used as a replacement
in critical components of larger constructions where Type 316L or 317L has failed by pitting,
crevice attack, or chloride stress corrosion cracking. In new construction, 254SMO has been found
in many cases to be a technically adequate and much less costly substitute for nickel-based alloys
and titanium.
254SMO is substantially stronger than the common austenitic grades, but is also characterized by high ductility and impact strength. 254SMO is readily fabricated and welded.
