Incoloy alloy 27-7MO is an advanced 7% molybdenum super-austenitic stainless steel offering corrosion resistance in most environments superior to 6% molybdenum super-austenitic stainless steels. In many environments Incoloy 27-7MO (UNS S31277) offers resistance approaching that of much more highly alloyed materials such as INCONEL alloys 625, 22, and C-276.
Incoloy 27-7MO products typically contain 27% nickel, 22% chromium, 7.2% molybdenum, and 0.34% nitrogen. By virtue of its content of molybdenum, chromium, and nitrogen, alloy 27-7MO offers excellent resistance to pitting and crevice corrosion. The nickel, nitrogen, and molybdenum provide resistance to reducing media while a high content of chromium offers resistance to oxidizing media. Incoloy 27-7MO performs well in mixed acid environments, especially those containing oxidizing and reducing acids.
