347H Stainless Steel Tubes - Quick Section Links
347H Stainless Steel Tubes
SUS 347H tube is a stainless-steel tubing that are used in high-temperature applications where durability, resistance to oxidation, along with long-term reliability are essential. This is the high-carbon variation of SUS 347 which has higher creep strength and performance in constant pressure and heat. It is a source of niobium that aids in reducing precipitation of carbide following welding, and also helps in preventing intergranular corrosion. These tubes can be used for heat exchangers, boilers refinery equipment, furnace components and power plants, petrochemical equipment and high-temperature pipe systems.
What are SUS 347H Tubes?
SUS 347H Tubes a type of stainless steel that is heat-resistant tubes that are designed to withstand the most demanding service conditions. They’re also known by the names of Stainless Steel 347H Tubes, UNS S34709 Tubes and DIN 1.4961 Tubes and SS 347H Tubes in different standards. The material is a good choice for welding due to its stability, oxidation resistance and mechanical strength when exposed to high temperatures. It is recommended to choose based on pressure, temperature the size of the tube wall thickness, as well as the conditions of service.
