SMO 254 is a super austenitic stainless steel alloy that boasts about 20% chromium, 18% nickel, 6% molybdenum, along with small amounts of nitrogen and copper. This well-balanced mix gives it a high PREN (Pitting Resistance Equivalent Number) of over 42.5, showcasing its excellent corrosion resistance. The alloy offers a tensile strength of around 650 MPa and a yield strength close to 300 MPa, along with good ductility and weldability, even in tough service conditions.
