Product Description

Alloy 254 (STAINLESS 6Mo - UNS S31254) Plate - 254SMo Stainless Steel Plate

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

Key Features of Inox 254SMo

As a super stainless steel, 254SMo represents a high-alloy stainless steel containing elevated levels of nickel, chromium, and molybdenum. The 6% molybdenum content provides exceptional local corrosion resistance, making it suitable for harsh conditions including seawater, aeration, gaps, 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 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
