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 nickelbased
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.
