Material Notes:

INCOLOY® alloy 25-6MO (UNS N08926/W.
Nr. 1.4529, formerly UNS N08925) is a
super-austenitic stainless steel containing
6% molybdenum and enhanced by an
addition of nitrogen. The nickel and
chromium contents of this alloy make it
resistant to a wide range of corrosive
environments. The alloy is especially resistant
to non-oxidizing acids such as sulfuric and
phosphoric. The high molybdenum content
and nitrogen provide resistance to pitting and
crevice corrosion, while copper enhances
resistance to sulfuric acid.
