Product Description
Prime Quality UNS S31254 Seamless Stainless Steel Pipes
Also known as 254 SMO, 1.4547, and 254SMO, this premium stainless steel is engineered for exceptional performance in demanding industrial applications.
Product Overview
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 features excellent resistance to uniform corrosion. With carbon content below 0.02%, it qualifies as pure austenitic stainless steel, and when carbon content is less than 0.01%, it can be classified as super austenitic stainless steel.
Key Features of 254SMo Stainless Steel
- High-alloy composition with elevated nickel, chromium, and molybdenum content
- 6% molybdenum content provides exceptional local corrosion resistance
- Superior resistance to pitting corrosion (PI ≥ 40) and stress corrosion
- Excellent performance in harsh conditions including seawater, aeration, gaps, and low-speed scouring
- Suitable replacement for nickel-based alloys and titanium alloys
- Outstanding high-temperature resistance and corrosion resistance surpassing 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
