Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 317L Pipes, proudly based in Cape Town, South Africa. This company is all about crafting top-notch austenitic stainless steel pipes that are built to withstand tough conditions, offering fantastic corrosion resistance and durability even in the harshest environments. The Stainless Steel 317L Pipes from Njabulo Stainless are known for their exceptional resistance to pitting, crevice corrosion, and oxidation, making them perfect for use in chemical, petrochemical, and marine settings. With state-of-the-art production facilities and rigorous quality control measures, they cater to various industries, including chemical processing, pharmaceuticals, oil and gas, and seawater applications, providing reliable and long-lasting piping solutions that adhere to international standards.
These pipes are primarily made up of iron, chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), featuring a low carbon content (maximum 0.03%) along with trace amounts of manganese and silicon. The inclusion of molybdenum significantly boosts their resistance to pitting and crevice corrosion, especially in environments rich in chlorides and oxidizing agents. With a tensile strength ranging from about 515 to 690 MPa and a yield strength of around 205 to 275 MPa, these pipes also showcase impressive elongation and toughness. They maintain outstanding mechanical stability and corrosion resistance, even in challenging chemical and marine conditions.
