Njabulo Stainless, located in Cape Town, South Africa, has built a solid reputation as a manufacturer and supplier of Stainless Steel 304L Flanges. They offer a diverse selection of flanges, including weld neck, slip-on, blind, and threaded types, all crafted to meet international standards. These flanges are engineered to ensure reliable and durable connections in piping systems across a variety of industries, such as petrochemical, food processing, pharmaceuticals, and marine. Njabulo Stainless is committed to precision manufacturing and using high-quality materials, resulting in flanges that perform exceptionally well even in tough conditions.
Stainless Steel 304L Flanges are crafted from a low-carbon variant of the 304 stainless steel alloy, which contains about 18–20% chromium and 8–12% nickel, with a maximum carbon content of 0.03%. This lower carbon content greatly enhances resistance to intergranular corrosion after welding, ensuring that the structural integrity of welded assemblies remains intact. These flanges boast a tensile strength of around 485 MPa and provide excellent corrosion resistance in various environments. Their ductility and toughness also make them suitable for both low and high-temperature applications.
