Njabulo Stainless is a top-notch manufacturer and supplier of Stainless Steel 348 Pipes, proudly based in Cape Town, South Africa. This company is all about crafting high-quality austenitic stainless steel pipes that excel in high-temperature and corrosive settings. The Stainless Steel 348 Pipes from Njabulo Stainless are designed to offer outstanding creep resistance, thermal stability, and corrosion resistance, making them perfect for critical industrial uses. With state-of-the-art manufacturing facilities and strict quality control measures, they cater to industries like power generation, chemical processing, petrochemical, and aerospace, providing reliable and durable piping solutions.
These Stainless Steel 348 Pipes mainly consist of iron, chromium (19–21%), nickel (9–13%), along with trace amounts of titanium, manganese, silicon, and carbon. The addition of titanium helps prevent carbide precipitation, which ensures they have a high resistance to intergranular corrosion during welding and exposure to high temperatures. These pipes boast a tensile strength of about 515–750 MPa, a yield strength of around 205–310 MPa, and impressive elongation properties. Their exceptional thermal stability, oxidation resistance, and toughness make them ideal for applications that require long-lasting performance in elevated temperatures.
