Incoloy 926 alloy (UNS N08926 / 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.

 

Incoloy 926 alloy bar 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. 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. One of the outstanding attributes of Incoloy 926 alloy bar is its resistance to environments containing chlorides or other halides. This alloy is especially suited to handle high-chloride environments such as brackish water, sea water, caustic chlorides and pulp mill bleach systems.
