1. Excellent Corrosion Resistance
904L offers a robust resistance to general corrosion and is designed for harsh chemical environments.
2. Resistance to Pitting and Crevice Corrosion
The higher molybdenum content increases the resistance to localized corrosion, which makes it useful in chloride-rich environments.
3. Excellent Acid Resistance
The copper content of 904L provides increased resistance to acid reduction, particularly sulfuric acid, under the proper conditions of service.
4. Good Weldability
The low carbon content can help reduce the precipitation of carbide and makes 904L an ideal choice for a wide range of welding fabrication processes when the appropriate processes are followed.
5. High Durability
This alloy’s blend of strength in the mechanical realm and corrosion resistance provides long-term use in the most demanding equipment for industrial use.
6. Good Formability
As an austenitic stainless metal, 904L typically has excellent ductility and is made using appropriate industrial processes.
