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.

Largest Stainless Steel 347 Tubing Supplier in Tunis, Tunisia

Stainless Steel 347 is an austenitic stainless steel alloyed with chromium and nickel, with the addition of niobium for enhanced stability. This composition prevents carbide precipitation during welding and high-temperature service, improving resistance to intergranular corrosion. SS 347 tubing offers good tensile strength, excellent toughness, and outstanding oxidation resistance at elevated temperatures. It is non-magnetic in the annealed condition and maintains its mechanical integrity under thermal stress, making it suitable for continuous high-heat applications.
