Product Description

254SMo Stainless Steel Tubes and Bars

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 is classified as pure austenitic stainless steel, and when carbon content is less than 0.01%, it qualifies as super austenitic stainless steel.

Key Features of 254SMo Stainless Steel

Super stainless steel with high nickel, chromium, and molybdenum content
Contains 6% molybdenum for exceptional local corrosion resistance
Excellent resistance to pitting corrosion (PI ≥ 40) and stress corrosion
Suitable replacement for nickel-based alloys and titanium alloys
Superior high-temperature 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
