Introduction
S31254, also 254SMO is a super Austenitic Stainless Steel. It is
designed with a combination of impact toughness resistance to
chloride stress corrosion cracking, and pitting and crevice
corrosion with strength that is twice that of the stainless steel
300 series.
A large number of field experiments and extensive use experience
show that even at slightly higher temperatures, S31254 stainless
steel pipe also has a high resistance to crevice corrosion in
seawater, and only a few types of stainless steel have this
performance. The corrosion resistance of S31254 stainless steel
tubes in acidic and oxidizing halide solutions such as those
required for paper bleaching production can be combined with the
corrosion resistance of nickel-based alloys in titanium alloys.
The S31254 stainless steel tube has a high nitrogen content, so its
mechanical strength is higher than other types of austenitic
stainless steel. In addition, it has high ductility and impact
strength and good weldability.
The high molybdenum content of S31254 stainless steel pipe enables
it to have a high oxidation rate during annealing, resulting in a
rougher surface than ordinary stainless steel after pickling.
However, this has no adverse effect on the corrosion resistance of
the steel
