Super-austenitic Stainless Steel INCOLOY alloy 926 UNS N08926 for fire system water purification system
INCOLOY® alloy 926 (W. Nr. 1.4529 ) 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.
INCOLOY alloy 926 is a fully austenitic alloy containing 6% molybdenum and offering excellent corrosion resistance in a wide variety of aggressive, aqueous environments. It replaces the conventional, austenitic stainless steels (AISI 316 and 317), where their capabilities are pushed to their performance limits. The alloy, therefore, falls into a “super austenitic stainless steel” category. It can also represent a cost-effective alternative to the higher nickel alloys in some marine and chemical processing environments.
