Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions
The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum.
3. Application
Some of the major applications of grade 904L stainless steels include:
Wiring in electrostatic precipitators,Oil refinery components
Seawater cooling devices,Gas scrubbing plants
Pulp and paper processing industries
Acetic, phosphoric and sulphuric acid processing plants
