Home > SMO 254 Tube Fittings
SMO 254 Tube Fittings are made from a super austenitic stainless steel alloy containing 19.5–20.5% chromium, 17.5–18.5% nickel, 6–7% molybdenum, and added nitrogen to enhance pitting and crevice corrosion resistance. This high-alloy composition provides outstanding stability in seawater, chlorides, and acidic environments. Mechanically, SMO 254 offers high tensile and yield strength, excellent toughness, and reliable elongation, even under elevated temperatures. The material’s superior corrosion resistance and structural integrity make these fittings ideal for demanding applications requiring long service life and consistent performance.
