Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 316L Fasteners based in Cape Town, South Africa. They specialize in delivering high-quality fasteners that are designed for strength, durability, and outstanding resistance to corrosion. Crafted from low-carbon austenitic stainless steel, these fasteners are built to withstand pitting, crevice, and intergranular corrosion, making them perfect for marine, chemical, and industrial uses. With excellent mechanical stability, precise dimensions, and superior weldability, Njabulo Stainless ensures that their products meet strict quality control and international standards, providing reliable performance and longevity across various industrial, structural, and commercial applications in South Africa.
Stainless Steel 316L Fasteners are made up of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and a low carbon content (≤0.03%), which boosts their corrosion resistance and prevents carbide precipitation. They boast a tensile strength of 485 MPa, a yield strength of 170 MPa, and an elongation of 40%, ensuring they are tough and durable. With a density of 8.0 g/cm³ and a melting range of 1370–1400°C, these fasteners maintain excellent mechanical stability and corrosion resistance even in harsh environments, making them ideal for demanding industrial, marine, and high-temperature applications.
