254SMo S31254 ASTM A789 F44 1.4547 Super Austenitic 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 offers excellent resistance to uniform corrosion. With carbon content below 0.02%, it qualifies as pure austenitic stainless steel, and when carbon content is under 0.01%, it can be classified as super austenitic stainless steel.
Key Features of 254SMo Stainless Steel
Super stainless steel represents a specialized category of high-alloy stainless steel containing elevated levels of nickel, chromium, and molybdenum. The most prominent example is 254SMo with 6% molybdenum content. The high molybdenum concentration provides exceptional local corrosion resistance, along with superior resistance to pitting corrosion (PI ≥ 40) and stress corrosion in demanding conditions including seawater, aeration, gaps, and low-speed scouring. This makes 254SMo an excellent alternative to nickel-based alloys and titanium alloys.
Additionally, 254SMo offers outstanding high-temperature resistance and corrosion performance that surpasses conventional 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 advanced 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 exhibits high ductility, excellent impact strength, and good weldability. While the high molybdenum content results in increased oxidation rates during annealing, leading to a slightly rougher surface after pickling compared to standard stainless steels, this characteristic does not compromise the material's corrosion resistance.
