Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 304H 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 Stainless Steel 304H Pipes apart is their higher carbon content compared to standard 304, which boosts their tensile strength, creep resistance, and thermal stability. With state-of-the-art manufacturing facilities and rigorous quality control measures, Njabulo Stainless caters to various industries, including chemical processing, petrochemical, power generation, marine, and food processing, providing robust and dependable piping solutions that can handle the toughest high-temperature demands.
These pipes are mainly made up of iron, chromium (18–20%), nickel (8–12%), and a higher carbon content (0.04–0.10%), along with trace amounts of manganese and silicon. The elevated carbon content not only enhances tensile strength and creep resistance at high temperatures but also ensures excellent corrosion resistance in both oxidizing and mildly corrosive environments. With a tensile strength ranging from about 515–700 MPa and a yield strength of around 205–310 MPa, these pipes also boast good elongation and toughness. They maintain outstanding thermal stability, oxidation resistance, and mechanical integrity even under prolonged high-temperature use.
