Njabulo Stainless, located in Cape Town, South Africa, has built a solid reputation as a reliable manufacturer and supplier of top-notch Stainless Steel 317/317L Forged Fittings. Known for their precision engineering and outstanding durability, this company caters to a variety of industries, providing stainless steel solutions that adhere to global standards. With a strong emphasis on innovation, corrosion resistance, and performance, Njabulo Stainless guarantees that their forged fittings are perfect for even the most demanding environments. Supported by state-of-the-art manufacturing facilities and a talented technical team, they consistently deliver products that surpass customer expectations in terms of quality, strength, and exceptional service.
Stainless Steel 317/317L Forged Fittings boast higher levels of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%) compared to standard stainless grades, which significantly boosts their resistance to corrosion and oxidation. The low carbon content in 317L enhances weldability and reduces the risk of carbide precipitation. These fittings showcase impressive mechanical properties, including a minimum tensile strength of 515 MPa, a yield strength of at least 205 MPa, and an elongation of around 35%. Their remarkable resistance to pitting, crevice corrosion, and chemical attacks makes them perfect for tough industrial and marine settings.
