The Stainless Steel 348/348H forged fittings are primarily made of iron, containing 17–19% chromium, 8–10% nickel, and titanium to boost high-temperature performance. The 348H grade features a slightly higher carbon content, enhancing its creep and stress-rupture strength at elevated temperatures. These alloys are known for their excellent oxidation and corrosion resistance, along with impressive tensile strength, toughness, and dimensional stability. The addition of titanium helps prevent carbide precipitation during welding or exposure to high temperatures, ensuring long-lasting reliability in critical applications where durability and thermal stability are crucial.
