High Light Corrosion Resistant 254 SMO TubingHigh Molybdenum S31254 PipeSuper Austenitic Seamless Tubing
254SMo Super Austenitic Stainless Steel
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 can be classified as super austenitic stainless steel.
Key Features of 254SMo Stainless Steel
  • High-alloy composition with elevated nickel, chromium, and molybdenum content
  • 6% molybdenum content provides exceptional local corrosion resistance
  • Superior resistance to pitting corrosion (PI ≥ 40) and stress corrosion
  • Excellent performance in harsh conditions including seawater, aeration, gaps, and low-speed scouring
  • Suitable replacement for nickel-based alloys and titanium alloys
  • Enhanced 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
  • High nitrogen content provides improved mechanical strength
  • Excellent ductility, impact strength, and weldability
