SS 904L Plates Features

• » Extreme Acid Resistance: The high nickel and chromium content, combined with the addition of copper, provides unmatched resistance to strong reducing acids, particularly sulfuric acid.
• » Superior Pitting & Crevice Protection: With a high molybdenum content, these plates offer exceptional resistance to localized attack in high-chloride environments like seawater and brackish water.
• » Resistance to Stress Corrosion Cracking (SCC): The 25% nickel content makes the alloy highly resistant to chloride-induced SCC, outperforming standard 300-series stainless steels.
• » Non-Magnetic Properties: As a super-austenitic grade, 904L remains non-magnetic even after heavy cold working or welding, essential for sensitive electronic and medical equipment.
• » Low Carbon "L" Grade: The low carbon chemistry prevents carbide precipitation during welding, ensuring the material retains full corrosion resistance in the heat-affected zone (HAZ).
• » Excellent Formability & Weldability: Despite its high alloy content, 904L can be welded using all standard methods and possesses excellent ductility for deep drawing and forming.
• » High Mechanical Toughness: Maintains superior toughness and impact strength from cryogenic temperatures up to 400°C, providing structural reliability in extreme conditions.
• » Long Service Life: Reduces downtime and replacement costs in highly aggressive chemical environments where standard stainless steels would suffer from rapid degradation.
