Home > Pipe Fittings > Stainless Steel 348H Pipe Fittings
Stainless Steel 348H Pipe Fittings are top-notch components crafted for piping systems that demand outstanding corrosion resistance, high-temperature strength, and long-lasting reliability. Thanks to titanium stabilization in 348H, these fittings effectively prevent intergranular corrosion, making them perfect for use in boilers, heat exchangers, pressure vessels, and industrial pipelines that operate under extreme temperatures and harsh chemical conditions.
These fittings are mainly made up of iron, chromium, nickel, and titanium. The chromium boosts corrosion resistance, while nickel enhances toughness and ductility. Titanium plays a crucial role in stabilizing the microstructure, ensuring that the fittings maintain their mechanical integrity even at elevated temperatures. With their impressive tensile strength, thermal stability, and resistance to creep, these fittings guarantee secure and leak-proof connections in high-pressure and high-temperature scenarios.
