These features
make it worth considering by designers, when deciding
whether to apply non-rusting non-alloy steel or ferritic
high-alloy steel with corrosion resistance guaranteed by
chromium. X2CrNi12 steel, unlike (Cr–Ni) austenitic steel,
which is characterized by better stress corrosion resistance
to chlorides but is not as applicable when intercrystalline
corrosion resistance is required.
