SMO 254 Pipes are made up of about 20% chromium, 18% nickel, 6% molybdenum, and 0.2% nitrogen, giving them a Pitting Resistance Equivalent Number (PREN) exceeding 42.5. This unique composition provides outstanding resistance to localized corrosion in seawater and other highly chlorinated settings. SMO 254 boasts a tensile strength of around 650 MPa, a yield strength of about 300 MPa, and impressive ductility with an elongation of roughly 35%. The alloy is non-magnetic, fully austenitic, and retains its strength and corrosion resistance even under high mechanical stress and elevated temperatures.
