Stainless Steel 348/348H Forged Fittings are top-notch components designed for piping systems that require outstanding corrosion resistance, high-temperature strength, and long-lasting reliability. With titanium stabilization in both the 348 and 348H grades, 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 primarily made up of iron, chromium, nickel, and titanium. The chromium offers excellent corrosion resistance, while nickel boosts toughness and ductility. Titanium plays a crucial role in stabilizing the microstructure, ensuring that the fittings maintain their mechanical integrity even at elevated temperatures. As a result, these forged fittings deliver impressive tensile strength, thermal stability, and creep resistance, guaranteeing safe, leak-proof connections in high-pressure and high-temperature scenarios.
