347H Stainless Steel Pipes

SUS 347H Pipes are steel pipes that are designed for high-temperature applications where normal stainless steel can lose its the strength of the material after a prolonged exposure to heat. This particular grade is enriched with niobium, which aids in controlling the formation of carbide and shields the material from intergranular rust following welding. The 347H pipes are typically utilized in heat exchangers, refineries, power plants, chemical plants, and in other areas where pressure, heat, and corrosion are all present during operations. It is a durable material when welded and is suitable for use in applications where the strength must be stable even at temperatures that are high.

What are SUS 347H pipes?

SUS 347H pipes are high-carbon stainless steel, niobium-stabilized pipes. This grade is similar to stainless steel 347; however, its higher content of carbon offers more strength in high-temperature applications. SUS 347H pipes are identified as UNS S34709 tubes as well as DIN 1.4961 Tubes that conform to various standards. The Niobium content can reduce the chance of precipitation of carbide that can happen after stainless steel has been subjected to heat from welding or high temperatures. They are available in welded and seamless versions and are utilized when toughness, heat resistance, and corrosion prevention are essential.
