Alloy 25-6M0 (UNS N08926) is a fully austenitic alloy containing 6% molybdenum and 0.290 nitrogen, which offers excellent corrosion resistance in a wide variety of aggressive, aqueous environments. It replaces conventional, austenitic stainless steels (UNS S31600 and S3 1700), where their capabilities are pushed to their performance limits. One of the outstanding attributes of alloy 25-6M0 is its resistance to environments containing chlorides or other halides. The alloy is
especially resistant to non-oxidizing acids such as sulfuric and phosphoric. Alloy 25-6M0 exhibits excellent resistance to sulfide stress cracking (hydrogen embrittlement) and chloride stress corrosion cracking in severe sour brine environments.
