SMO 254 Foil is a top-notch austenitic stainless steel product celebrated for its remarkable corrosion resistance, strength, and durability, especially in tough environments. Thanks to its high levels of chromium, molybdenum, and nitrogen, SMO 254 stands out with exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. This makes it a perfect fit for chemical processing, marine, and offshore applications. These foils are crafted with precision, ensuring uniform thickness, a smooth surface finish, and excellent formability, which guarantees reliable performance in critical situations. SMO 254 Foil beautifully combines corrosion resistance, strength, and flexibility, making it ideal for gasket materials, heat exchangers, chemical equipment linings, and other industrial applications that demand long-lasting, high-performance stainless steel.
The composition of SMO 254 Foil primarily includes iron, chromium (20–22%), nickel (18–20%), molybdenum (6–7%), and nitrogen, which together provide outstanding corrosion resistance in environments rich in chlorides and oxidizing agents. Its mechanical properties boast a tensile strength of about 620–750 MPa, a yield strength around 310–450 MPa, and good elongation, ensuring both toughness and durability. The austenitic microstructure, enhanced by nitrogen and molybdenum, offers excellent resistance to localized corrosion and stability at high temperatures. This unique blend of properties allows SMO 254 Foil to maintain its structural integrity while offering the flexibility and formability needed for precision fabrication in demanding industrial settings.
