Kabby Flanges, a reputable manufacturer and supplier located in Abuja, Nigeria, is dedicated to crafting top-notch Stainless Steel 348 Flanges that excel in high-temperature and corrosive settings. These flanges are enhanced with niobium and tantalum, providing remarkable resistance to intergranular corrosion and oxidation. With a commitment to precision and global quality standards, Kabby Flanges guarantees that every product is durable, strong, and reliable. Stainless Steel 348 Flanges find their place in various industries, including petrochemical, power generation, and marine engineering, where heat and corrosion resistance are crucial for long-lasting and efficient performance.
The composition of Stainless Steel 348 Flanges includes chromium (17–19%), nickel (9–13%), niobium (8–10×C%), and tantalum, which together offer outstanding resistance to intergranular corrosion and high-temperature oxidation. They boast a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, ensuring excellent mechanical stability. The incorporation of niobium and tantalum also improves resistance to carbide precipitation during welding. These flanges maintain good ductility, toughness, and weldability, making them reliable under extreme thermal and mechanical stress.
