904L is a high-alloy austenitic stainless steel with low carbon content.
The grade is intended for use under severe corrosive conditions. It has
been application proved over many years and was originally developed to
resist corrosion in dilute sulfuric acid. It is standardized and
approved for pressure vessel use in several countries. Structurally,
904L is fully austenitic and is less sensitive to precipitation ferrite
and sigma phases than conventional austenitic grades with high
molybdenum content. Characteristically, due to the combination of
relatively high contents of chromium, nickel, molybdenum and copper 904L
has good resistance to general corrosion, particularly in sulfuric and
phosphoric conditions.
