The high content of alloying elements in 904L gives the alloy exceptionally good resistance to uniform corrosion.
Alloy 904L is a high-alloy austenitic stainless steel known for its exceptional corrosion resistance in aggressive environments. This material is particularly effective against sulfuric acid and chloride attack, making it suitable for use in harsh conditions where other stainless steels may fail. Alloy 904L combines molybdenum and copper, enhancing its ability to resist pitting and crevice corrosion.

Fractional distillation of tall oil often needs better material than 316L or even the more frequently used 317LMN. In these hot concentrated caustic solutions, the corrosion resistance is mainly determined by the nickel content of the material. With a nickel content of 25%, 904L has proven to be a good alternative to most conventional stainless steels.
Conventional stainless steels such as 304L and 316L are susceptible to chloride stress corrosion cracking (SSC) under certain conditions. Resistance to SSC increases with the increased content of nickel and molybdenum. Therefore, the higher performance austenitic stainless steels such as 904L have very good resistance to SSC. The table in the upper right corner shows resistance to SSC in a chloride solution under evaporative conditions. High performance austenitic steels and duplex stainless steels clearly outperform 316L.
