**Stainless Steel 348H Pipe Fittings** primarily consist of 18–20% chromium, 8–11% nickel, along with added columbium (niobium) and a higher carbon content (up to 0.10%) compared to standard 348. This unique composition enhances creep strength and high-temperature stability. The fittings boast a tensile strength of approximately 515 MPa, a yield strength of around 205 MPa, and exhibit good elongation and ductility. SS 348H effectively resists intergranular corrosion and retains its mechanical integrity even after extended exposure to high temperatures. These characteristics make it a dependable option for applications that demand strength, oxidation resistance, and weldability under thermal stress.
