Super Austenitic Stainless Steel Pipe 254SMo with High Molybdenum Content for Corrosion Resistance

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 offers excellent resistance to uniform corrosion. With carbon content below 0.02%, it qualifies as pure austenitic stainless steel, and when carbon content is under 0.01%, it is classified as super austenitic stainless steel.

254SMo represents a category of super stainless steel distinguished by its high alloy content of nickel, chromium, and molybdenum. The 6% molybdenum content provides exceptional local corrosion resistance, making it suitable for harsh conditions including seawater, aeration, gap corrosion, and low-speed scouring environments.

• Excellent pitting corrosion resistance (PI ≥ 40) and stress corrosion cracking resistance
• Superior alternative to nickel-based alloys and titanium alloys
• Enhanced high-temperature and corrosion resistance compared to standard 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
• Improved mechanical strength due to high nitrogen content
• High ductility, impact strength, and excellent weldability
