Key Features
1. Superior Corrosion Resistance
904L stainless steel offers exceptional resistance to sulfuric acid, phosphoric acid, and other aggressive chemicals. It performs far better than standard grades like 304 or 316 in highly corrosive environments.
2. Excellent Resistance to Crevice & Pitting Corrosion
Thanks to its enhanced molybdenum content, this material effectively prevents localized corrosion, making it ideal for chloride-rich and marine-like conditions.
3. High Purity & Stability
With very low carbon content, 904L reduces the risk of intergranular corrosion, ensuring stable performance in welded structures and high-temperature applications.
4. Good Weldability & Fabrication
904L plates and sheets can be easily welded and processed using standard methods, allowing flexible manufacturing for complex equipment and structures.
5. Outstanding Durability
Its strong resistance to oxidation and corrosion ensures a long service life, reducing maintenance costs and downtime.
Application Scenarios
1. Chemical Processing Industry
Widely used in reactors, heat exchangers, pipelines, and tanks that handle strong acids and corrosive media.
2. Acid Storage & Transportation
Ideal for manufacturing acid storage tanks, tank liners, and transport containers, especially for sulfuric acid and phosphoric acid.
3. Pharmaceutical & Food Equipment
Due to its high cleanliness and corrosion resistance, it is suitable for pharmaceutical reactors, storage vessels, and sanitary equipment.
4. Flue Gas Desulfurization (FGD) Systems
Commonly used in power plant flue gas treatment systems, where materials must withstand acidic condensates and harsh gases.
5. Marine & Coastal Environments
Suitable for components exposed to seawater or chloride environments, where corrosion resistance is critical.
Processing & Surface Options
