Home > Stainless Steel 904L Tube Fittings
Stainless Steel 904L tube fittings comprise 25% chromium, 20% nickel, 4.5% molybdenum, and trace amounts of copper. This high alloy content provides excellent resistance to corrosion, especially in acidic environments, and enhances strength and durability. Properties include high pitting and crevice corrosion resistance, good formability, and resistance to chloride-induced stress corrosion cracking. Advantages of 904L tube fittings include their suitability for harsh environments, exceptional longevity, and minimal maintenance, making them ideal for chemical processing, marine, and petrochemical industries.
