AISI 904L (1.4539, UNS N08904) is an austenitic stainless steel with high corrosion resistance. Nickel (20%), molybdenum (4.3%) and copper (1.5%) in AISI 904L (1.4539, UNS N08904), It is an excellent choice for most applications using moderate to severe corrosive solutions. The AISI 904L (1.4539, UNS N08904) features improved stress corrosion resistance. The AISI 904L (1.4539, UNS N08904) alloy is especially used in sulfuric and phosphoric acid applications.

 AISI 904L (1.4539, UNS N08904) is a super austenitic stainless steel developed for medium to high corrosion resistance in a wide range of environments. AISI 904L (1.4539, UNS N08904) is a high alloy chemical composition thanks to its high resistance to corrosion corrosion cracking, tingling resistance and overall corrosion resistance.

AISI 904L (1.4539, UNS N08904) was specifically developed for working in environments containing sulfuric acid. AISI 904L (1.4539, UNS N08904) is also resistant to other organic acids such as hot phosphoric acid and many organic acids.

AISI 904L (1.4539, UNS N08904) CORROSION RESISTANCE

 AISI 904L (1.4539, UNS N08904) was originally developed for use in dilute sulfuric acid containing media. AISI 904L (1.4539, UNS N08904) is one of the few alloys that will give full resistance in such environments to 95 ° C and 100% mixing ratios. Wear resistance in hot concentrate caustic solutions depends on the nickel content of the alloy, and the AISI 904L (1.4539, UNS N08904) exhibits very high resistance to these environments due to its high nickel content.
