Product Description

NPS 1 Inch (O.D. 33.4mm) x Sch. 40 x 6M Alloy 254 (Stainless 6Mo - UNS S31254) Pipe

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 below 0.01%, it qualifies as super austenitic stainless steel.

Features of Inox 254SMo

Super stainless steel represents a specialized category of stainless steel. Unlike conventional stainless steels, 254SMo is a high-alloy stainless steel containing elevated levels of nickel, chromium, and molybdenum. The most notable characteristic is its 6% molybdenum content, which provides exceptional local corrosion resistance.

Excellent resistance to pitting corrosion (PI ≥ 40) and stress corrosion in harsh environments including seawater, aeration, gaps, and low-speed scouring
Suitable replacement for nickel-based alloys and titanium alloys in many applications
Superior high-temperature resistance and corrosion resistance compared to 304 stainless steel
Stable austenitic metallurgical structure ensures reliable performance
High crevice corrosion resistance in seawater, even at elevated temperatures
Strong corrosion resistance in acidic solutions and oxidizing halide solutions comparable to nickel-based alloys and titanium
Enhanced mechanical strength due to high nitrogen content
High ductility, impact strength, and excellent weldability
