These SMO 254 Pipes are primarily made up of iron, chromium (20–22%), nickel (18–20%), molybdenum (6–7%), and nitrogen (0.2–0.3%), along with trace amounts of manganese, silicon, and carbon (capped at 0.02%). The elevated levels of chromium, molybdenum, and nitrogen grant them outstanding resistance to pitting and crevice corrosion, while also providing excellent mechanical strength and durability. These pipes showcase a tensile strength of about 600–800 MPa, a yield strength of around 300–500 MPa, and impressive elongation and toughness. Their remarkable corrosion resistance makes them perfect for harsh chemical and seawater environments.
