These flanges are made from a blend of chromium, nickel, and niobium, which gives them outstanding resistance to intergranular corrosion. The increased carbon content boosts their high-temperature strength and creep resistance. With impressive tensile strength, good toughness, and excellent stability during thermal cycling, SS 347H maintains its mechanical integrity even when exposed to high temperatures and harsh conditions for extended periods. Thanks to their strong weldability and formability, this alloy guarantees reliable performance in applications that demand structural durability, oxidation resistance, and long-term thermal stability.
