Njabulo Stainless is a top-notch manufacturer and supplier of Stainless Steel 316 Pipes, proudly based in Cape Town, South Africa. This company is all about crafting high-quality austenitic stainless steel pipes that stand up to corrosion, wear, and the toughest environments. Their Stainless Steel 316 Pipes are well-known for their outstanding resistance to pitting, crevice corrosion, and chemical damage, making them perfect for use in chemical, petrochemical, marine, and food-processing sectors. With state-of-the-art manufacturing facilities and strict quality control measures, Njabulo Stainless delivers reliable and durable piping solutions that comply with international industrial standards.
These Stainless Steel 316 Pipes are mainly made up of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), along with trace amounts of manganese, silicon, and carbon (up to 0.08%). The inclusion of molybdenum 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 they exhibit excellent elongation and toughness. They maintain impressive mechanical stability, oxidation resistance, and corrosion resistance, even in chemically aggressive and high-temperature situations.
