Alloy Details
Stainless steel 904L alloy is the super austenitic SS that is developed for the average to the high corrosion resistance at the wider ranges of processing atmosphere. The combination of alloying elements like nickel, chromium, copper, and molybdenum is assuring excellent resistance to corrosion. With the highly alloyed chemistry, 4.5% of molybdenum and 25% of nickel alloy, chloride stress corrosion cracking and pitting and general corrosion resistance becomes possible.
Alloy 904L is developed for withstanding the atmosphere that is containing the diluted sulfuric acid. It is also offering resistance ability to inorganic acid like hot phosphoric and organic acid as well. The alloy with the help of standard shop fabrication process can be welded easily.
