The 904L nickel alloy is a high-alloy austenitic stainless steel with low carbon content. Similar with other frequently used CrNi austenitic steel, the alloy 904L has excellent resistance to pitting and crevice corrosion, stress corrosion cracking and intergranular corrosion. In addition to this, it is also readily to be fabricated and welded.

The low carbon alloy can be used for oil and petrochemical equipment such as reactor, storage and transportation equipment for sulfuric acid, flue gas desulfurization unit in power plant, scrubber and fan in organic acid processing system, etc.
