254SMo is an austenitic stainless steel specifically developed for use in halide-containing environments such as seawater. This steel demonstrates superior performance particularly in halide-containing acids and features excellent resistance to uniform corrosion. With carbon content below 0.02%, it qualifies as pure austenitic stainless steel, and when carbon content is less than 0.01%, it can be classified as super austenitic stainless steel.

• High-alloy stainless steel containing elevated nickel, chromium, and molybdenum content
• 6% molybdenum content provides exceptional local corrosion resistance
• Excellent resistance to pitting corrosion (PI ≥ 40) and stress corrosion in harsh conditions
• Suitable replacement for nickel-based alloys and titanium alloys
• Superior high-temperature resistance and corrosion resistance compared to 304 stainless steel
• Stable austenitic metallurgical structure
• High crevice corrosion resistance in seawater, even at elevated temperatures
• Strong corrosion resistance in acidic solutions and oxidizing halide solutions
• Enhanced mechanical strength due to high nitrogen content
• High ductility, impact strength, and excellent weldability

• Ocean: Marine structures in sea environments, seawater desalination, marine aquaculture, seawater heat exchange
• Environmental Protection: Flue gas desulfurization for thermal power generation, wastewater treatment
• Energy: Nuclear power generation, comprehensive coal utilization, ocean wave power generation
• Petrochemical Industry: Refining operations, chemical equipment
