Super Austenitic S31254 Plate

Product Description
S31254 Stainless Steel Specifications F44 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 also features 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.
Features of Inox 254SMo
Super stainless steel represents a specialized category of stainless steel distinguished from ordinary grades by its high alloy content of nickel, chromium, and molybdenum. The most prominent example is 254SMo with 6% molybdenum content, which provides exceptional local corrosion resistance. This stainless steel offers superior resistance to pitting corrosion (PI ≥ 40) and stress corrosion in demanding conditions including seawater, aeration, gaps, and low-speed scouring, making it an excellent alternative to nickel-based alloys and titanium alloys.
Additionally, 254SMo exhibits outstanding high-temperature resistance and corrosion resistance capabilities that surpass those of 304 stainless steel. From a metallurgical perspective, special stainless steel maintains a stable austenitic structure.
Extensive field testing and practical experience confirm that 254SMo maintains high crevice corrosion resistance in seawater, even at elevated temperatures—a characteristic shared by only a few stainless steel types. In acidic solutions and oxidizing halide solutions used in paper bleaching applications, 254SMo demonstrates corrosion resistance comparable to the most resistant nickel-based alloys and titanium alloys.
The high nitrogen content in 254SMo provides enhanced mechanical strength compared to other austenitic stainless steels. The material also features high ductility, impact strength, and excellent weldability. While the high molybdenum content results in increased oxidation during annealing and a rougher surface after pickling compared to conventional stainless steels, this does not compromise the material's corrosion resistance properties.
