Stainless Steel 347 Tubing is an austenitic stainless steel with a composition of 17–20% chromium, 9–13% nickel, and columbium (niobium) stabilization for resistance to intergranular corrosion. The stabilization prevents carbide precipitation on exposure to welding and high temperatures. The tubing provides a tensile strength of 515–750 MPa and yield strength of approximately 205 MPa. It has great mechanical properties and resistance to oxidation in environments up to 870°C and, therefore, is used best in systems that are cycled through repeated heating and cooling or pressure cycles.

Stainless Steel 347 tubing is an austenitic stainless steel that’s stabilized with niobium (columbium) to guard against intergranular corrosion. It typically contains around 17–19% chromium and 9–13% nickel, along with trace elements of carbon, manganese, and silicon. This unique composition grants it excellent corrosion resistance, impressive tensile strength, and good creep resistance even at high temperatures. Additionally, Stainless Steel 347 tubing boasts superior weldability and dimensional stability, making it perfect for use in aggressive chemical environments and high-temperature applications.
Laila Pipes and Tubes, one of the largest suppliers of Stainless Steel 347 Tubing in Muscat, OMAN, offers a comprehensive range of high-quality pipes and tubes suitable for various industrial applications. Their extensive inventory and commitment to exceptional service make them a go-to choice for stainless steel products in the region.
You’ll find Stainless Steel 347 tubing widely utilized in industries that demand high corrosion resistance and strength under elevated temperatures.
