Home > Pipe Fittings > Stainless Steel 347H Pipe Fittings
Stainless Steel 347H Pipe Fittings are top-notch components crafted for piping systems that demand outstanding corrosion resistance, impressive high-temperature strength, and long-lasting reliability. Thanks to the addition of niobium, 347H effectively prevents intergranular corrosion, making these fittings perfect for use in boilers, heat exchangers, pressure vessels, and industrial piping systems that operate in extreme temperatures and harsh chemical environments.
These fittings are primarily made up of iron, chromium, nickel, and niobium. The chromium offers excellent corrosion resistance, while nickel boosts toughness and ductility. Niobium plays a crucial role in stabilizing the microstructure, ensuring that the fittings maintain their mechanical integrity even at elevated temperatures. With their superior tensile strength, thermal stability, and resistance to creep, these fittings guarantee secure and leak-proof connections in high-pressure and high-temperature settings.
