Composition and Characteristics
904L stainless steel's outstanding performance is attributed to its carefully balanced chemical composition, which includes:
Chromium (Cr):19-23%
Nickel (Ni):23-28%
Molybdenum (Mo):4-5%
Copper (Cu):1-2%
Carbon (C):0.02% max
Manganese (Mn):2% max
Silicon (Si):1% max
Phosphorus (P):0.045% max
Sulfur (S):0.035% max
The high chromium and nickel content, combined with significant amounts of molybdenum and copper, gives 904L stainless steel its superior resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments. Additionally, the low carbon content ensures that the alloy maintains its resistance to sensitization and intergranular corrosion after welding or thermal exposure.
