Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 316H Pipes, proudly based in Cape Town, South Africa. The company focuses on crafting top-notch austenitic stainless steel pipes that are built to excel in high-temperature and corrosive settings. What sets Njabulo Stainless’s 316H Pipes apart is their higher carbon content compared to standard 316, which enhances their strength and creep resistance when exposed to elevated temperatures. With state-of-the-art manufacturing facilities and rigorous quality control measures, the company caters to various industries, including chemical processing, petrochemical, power generation, marine, and oil and gas, providing robust and dependable piping solutions for challenging industrial needs.
These Stainless Steel 316H Pipes are mainly made up of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), along with a higher carbon content (0.04–0.10%) and trace amounts of manganese and silicon. The increased carbon not only boosts tensile and yield strength but also ensures excellent corrosion resistance in environments rich in chlorides and oxidizing agents. These pipes boast a tensile strength of about 515–700 MPa, a yield strength of around 215–275 MPa, and demonstrate good elongation and toughness. They also retain strong oxidation resistance, thermal stability, and mechanical integrity even under prolonged high-temperature conditions.
