When it comes to composition, Stainless Steel 347H Pipe Fittings are primarily made up of chromium (17–19%) and nickel (9–13%), with niobium added to prevent intergranular corrosion. The higher carbon content boosts their strength at elevated temperatures and enhances creep resistance. Mechanically, 347H fittings shine with excellent tensile and yield strength, good ductility, and reliable thermal stability. These characteristics ensure that the fittings maintain their structural integrity even when exposed to high temperatures, thermal cycling, and mechanical stress, making them perfect for demanding industrial settings.
