Avesta 254 SMO with World Wide Shipping
Avesta Sheffield 254 SMO® (UNS S31254) is an austenitic stainless
steel that has very high resistance to pitting and crevice corrosion
due to its high molybdenum content. The metal was designed for the
use in halide-containing environments such as seawater. 254 SMO also
has good resistance to uniform corrosion and is superior to
conventional stainless steels especially in acids containing
halides.
The elevated levels of molybdenum in particular but also of chromium
and nitrogen endow 254 SMO with extremely great resistance to
pitting and crevice corrosion. The addition of copper provides
increased resistance in certain acids. Due to its relatively high
nickel content in addition with the high levels of chromium and
molybdenum 254 SMO has excellent resistance to stress corrosion
cracking.
Even highly alloyed stainless steels have limited applicability in
environments which have halide ions, e.g. chloride, bromide and
fluoride solutions. It is for this reason it has often been
necessary to use such expensive materials such as nickel based
alloys or titanium for these environments. 254 SMO was developed
with a view of offering a less expensive alternative to the
conventional pricier alloys.
Its high nitrogen content 254 SMO has higher mechanical strength
than most other austenitic stainless steels. Similar to these, 254
SMO is characterized by high ductility and impact strength as well
as good weldability. The high molybdenum content of 254 SMO can lead
to an increased oxidation rate at annealing and as a consequence a
rougher surface finish after pickling than standard stainless
steels.
Due to its excellent anti-corrosive behaviors, many types of
fasteners can be made from Avesta 254 SMO. Lightning Bolt has the
capabilities to provide you with Avesta 254 fasteners such as hex
bolts, nuts, washers, studs, and special orders.
