Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 317 Pipes, proudly based in Cape Town, South Africa. The company focuses on crafting top-notch austenitic stainless steel pipes that excel in corrosion resistance and durability, even in tough environments. Their Stainless Steel 317 Pipes are designed to withstand pitting, crevice corrosion, and chemical attacks, making them perfect for use in chemical, petrochemical, and marine sectors. With state-of-the-art production facilities and rigorous quality control measures, Njabulo Stainless caters to industries like chemical processing, pharmaceuticals, oil and gas, and seawater systems, providing dependable and long-lasting piping solutions that adhere to international standards.
These Stainless Steel 317 Pipes are mainly made up of iron, chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), along with trace amounts of manganese, silicon, and carbon (up to 0.08%). The inclusion of molybdenum greatly boosts their resistance to pitting and crevice corrosion, especially in environments rich in chlorides and oxidizing agents. These pipes boast a tensile strength of about 515–690 MPa, a yield strength of around 205–275 MPa, and impressive elongation and toughness. They maintain excellent mechanical stability and corrosion resistance, even under harsh chemical, marine, and high-temperature conditions.
