AISI 904L Stainless Steel Coil N08904 1.4539

Composition and Characteristics

The unique properties of 904L stainless steel are attributed to its carefully balanced chemical composition. The typical chemical composition 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

This composition ensures that 904L stainless steel has outstanding resistance to a wide range of corrosive environments, including reducing acids and chloride-rich settings. The addition of copper enhances its resistance to sulfuric acid, while the high chromium and nickel content provide robust protection against oxidation and corrosion.
