The composition of SMO 254 Forged Fittings primarily includes iron, along with 20–22% chromium, 18–20% nickel, 6–7% molybdenum, 0.2–0.5% nitrogen, and trace amounts of manganese, copper, and silicon. This super austenitic stainless steel alloy is known for its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in environments rich in chloride. On the mechanical side, these fittings boast a tensile strength of about 700 MPa and a yield strength of around 320 MPa, along with impressive toughness and elongation. The high levels of alloying elements contribute to their outstanding strength, weldability, and corrosion resistance, even in aggressive chemical and marine conditions.
