| High Light | Super Austenitic Stainless Steel Pipe ，Corrosion Resistant 254SMo Pipe ，High Molybdenum Content Stainless Steel Tube | ||
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 is classified as super austenitic stainless steel.
254SMo represents a category of super stainless steel distinguished by its high alloy content of nickel, chromium, and molybdenum. The 6% molybdenum content provides exceptional local corrosion resistance, making it suitable for harsh conditions including seawater, aeration, gap corrosion, and low-speed scouring environments.
