Njabulo Stainless stands out as a top-notch manufacturer and supplier of Stainless Steel 316L Flanges in Cape Town, South Africa. We pride ourselves on delivering high-quality products that are designed for strength, reliability, and exceptional resistance to corrosion. Crafted from low-carbon austenitic stainless steel, these flanges are incredibly resistant to pitting, crevice, and intergranular corrosion, making them perfect for use in chemical, petrochemical, and marine settings. Our Stainless Steel 316L Flanges offer outstanding weldability, durability, and precise dimensions, ensuring secure connections in piping systems. At Njabulo Stainless, we uphold rigorous quality standards, providing flanges that meet international specifications for long-lasting performance in tough industrial and structural environments.
Stainless Steel 316L Flanges are made up of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), with a low carbon content (≤0.03%) that boosts corrosion resistance and prevents carbide precipitation. This alloy boasts a tensile strength of around 485 MPa, a yield strength of 170 MPa, and an elongation of 40%, ensuring excellent toughness and durability. With a density of 8.0 g/cm³ and a melting range of 1370–1400°C, these flanges are well-suited for high-pressure and high-temperature applications, maintaining mechanical and chemical stability even in harsh environments.
