Corrosion Resistant S31254 Pipe

Product Description

ASTM A790 S31254 Seamless Stainless Steel Pipe (SS EN X1CrNiMoN20-18-7/ 1.4547)

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

Super stainless steel represents a specialized category of stainless steel, distinguished from ordinary grades by its high alloy content including elevated levels of nickel, chromium, and molybdenum. The most prominent example is 254SMo with 6% molybdenum content.

Exceptional local corrosion resistance due to high molybdenum content
Superior resistance to pitting corrosion (PI ≥ 40) and stress corrosion 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 comparable to nickel-based alloys and titanium
Enhanced mechanical strength from high nitrogen content
High ductility, impact strength, and excellent weldability
