AISI 904L is a super-austenitic chromium-nickel stainless steel. Differs in the increased corrosion resistance
in strong aggressive environments. Also, AISI 904L steel exhibits special resistance in sea water, has high resistance
to pitting, crevice and intergranular corrosion. It should be noted that the level of anti-corrosion resistance of
AISI 904 L is higher than that of metals of the chromium-nickel-molybdenum group.

The high nickel content of the composition provides AISI 904L with excellent resistance to stress corrosion cracking.
Copper contributes to better acid resistance, especially in the most aggressive medium strength range.
