Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 314 Tubing, proudly based in Cape Town, South Africa. The company has built a solid reputation for providing top-notch austenitic stainless steel tubing that performs exceptionally well in high-temperature and oxidizing environments. Their Stainless Steel 314 Tubing boasts outstanding resistance to heat scaling and corrosion, making it a perfect fit for industrial and thermal processing applications. Thanks to cutting-edge manufacturing technology and strict quality control, Njabulo Stainless guarantees precision-engineered tubing that meets international standards for strength, reliability, and durability, even in the toughest operating conditions.
The composition of Stainless Steel 314 Tubing includes iron, chromium (23–26%), nickel (19–22%), silicon (1.5–3%), and a low carbon content (maximum 0.25%). The high levels of chromium and nickel significantly boost oxidation resistance and mechanical stability at elevated temperatures, while silicon contributes to enhanced strength and heat resistance. This tubing showcases a tensile strength of about 550–750 MPa and a yield strength of around 250–350 MPa, along with excellent creep resistance, making it ideal for high-temperature applications.
