INCOLOY alloy 27-7MO is an advanced 7% molybdenum superaustenitic stainless steel offering corrosion resistance in most environments superior to 6% molybdenum superaustenitic stainless steels. In many environments alloy 27-7MO offers resistance approaching that of much more highly alloyed materials such as INCONEL alloys 625, 22, and C-276.

Applications for INCOLOY alloy 27-7MO are found in the pollution control, power, marine, chemical processing, pulp and paper and oil and gas industries. Alloy 27-7MO offers a unique combination of corrosion resistance, high strength and ease of fabrication at an economical price.
