About 254SMo 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 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.

Key Features of Inox 254SMo

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
