Stainless Steel 347 Pipes are pipes made from an austenitic stainless steel alloy containing chromium, nickel, and other elements. It is known for its excellent corrosion resistance, even under extreme temperatures, by forming a thin oxide layer on its surface. This oxide layer protects the pipe from exposure to water and other environmental conditions. The addition of niobium in the alloy improves intergranular corrosion resistance, meaning that welds are less likely to corrode or fail prematurely due to the presence of aggressive substances in the environment. The high creep strength also makes these stainless steel pipes ideal for applications with elevated temperatures ranging between 800°C – 1100°C (1472°F – 2012°F). The stainless steel 347 pipe is stabilized against chromium carbide formation by the addition of columbium and tantalum.Since these elements have a stronger affinity for carbon than chromium, columbium-tantalum carbides precipitate within the grains instead of forming at the grain boundaries. Our 347 Stainless Steel is mainly used for applications requiring intermittent heating between 800ºF (427ºC) and 1650ºF (899ºC) or for welding under conditions which prevent a post-weld anneal.

Jinie Technology (Jiangsu) Co., LTD is a supplier of a wide range of piping products. And our ASTM A312 Tp347 Pipe products are much durable, robust and harder. So they hardly break under high temperature. The resistance properties allow the UNS S34700 Welded Pipe to be welded heavily without leading to localized corrosion because of the less intergranular corrosion resulting from carbide precipitation. Due to the high corrosion resistant nature of the material, the pipes are used in ovens, piping with storage tanks, valves, containers and in machine parts. The DIN 1.4550 SS Tubing that we provide is of superior quality. We will provide our customers with more details for their inquiries. Manufacturers of stainless steel 347 pipes make them with a higher level of corrosion resistance than steel 321 grade. This steel has been stabilised with niobium and tantalum to provide prolonged corrosion resistance. Because of the stabilisation, there is significantly less intergranular precipitation in the austenitic steel during welding. Our Stainless steel 347 Pipe products are suitable for high-temperature, demanding applications requiring more welding.
