Stainless Steel 904L Plates, UNS N08904 Sheets

What is Stainless Steel 904L?

Designed especially for use in very corrosive surroundings Stainless Steel 904L beats grades like 316L among others. Its low carbon concentration is suitable for built structures since it maintains corrosion resistance and stops carbide precipitation during welding.

Applications of Stainless Steel 904L Plates & Sheets

• Chemical Processing: Ideal for control of sulphuric and phosphorous acids in reactors, heat exchangers, and storage tanks.
• Oil & Gas: Utilised in equipment and offshore platforms that are subjected to seawater and sour gas.
• Marine Engineering: Great for maritime hardware, desalination facilities, and seawater cooling systems.
• Power Generation: preferred for parts used in condensers and flue gas desulfurization (FGD) systems.
• Pharmaceuticals: appropriate for corrosive processing agents in sterile settings.
• Pulp & Paper: Utilised in the treatment of caustic liquor in bleaching plants.

Key Advantages of Stainless Steel 904L

Major Benefits of Using Stainless Steel 904L:

• Excellent Corrosion Resistance: Clearly opposes both general and localised forms of corrosion including pitting and crevice corrosion even in difficult situations.
• Excellent Weldability & Fabrication: Using traditional techniques without risk of sensitizing, can be easily shaped and welded depending on low carbon content.
• Impressive High Temperature Performance: Remaining strength and corrosion resistance at rather high temperatures is impressive high-temperature performance.
• Superior Stress Corrosion Cracking Resistance: Strong resistance against chloride-induced stress corrosion cracking (SCC) makes this material fit for maritime and chemical processing systems.
• Non Magnetic In Annealed State: Because of its entirely austenitic structure—which is essential for many uses—904L remains non-magnetic in Annealed State.
• Minimal Maintenance Requirements: Less replacements and repairs resulting from its durability helps to save long-term costs.

How to Select the Right 904L Product

Key Considerations for Selecting the Right 904L Product:

• Service Environment: Assess exposure to corrosive substances, operating temperature, and pressure levels.
• Product Form: Select from available forms such as plate, sheet, pipe, tube, or bar based on application needs.
• Dimensions: Confirm the required thickness, width, and length to match project specifications.
• Surface Finish: Choose the appropriate finish (No. 1, 2B, BA, No. 4, or Mirror) for functional or aesthetic requirements.
• Standards & Certification: Ensure compliance with standards like ASTM and EN; request Mill Test Certificates (MTCs) when needed.
• Supplier Reputation: Work with trusted suppliers who offer quality assurance, proper documentation, and reliable customer support.
