SA213 TP347 / 347H is a seamless ferrite and austenite alloy SS (stainless steel) boiler tube used for superheater and heat exchanger tubes.
SS 347H High Pressure Pipe is mainly composed of iron, chromium, nickel and other elements, among which the chromium content is relatively high, which makes it have good corrosion resistance, especially in acid, alkali, salt and other solutions. It can show good corrosion resistance.
In addition, TP347H Seamless Tube also has good processing and welding properties, easy to process and weld. In the welding process, choosing appropriate welding materials and process parameters, taking effective measures to prevent the occurrence of welding defects, can ensure the quality of the welded joint and improve the service life.
