The strength of our 347/347H seamless pipes comes from a specific composition, stabilized with columbium to resist carbide precipitation. This gives these pipes exceptional resistance to intergranular corrosion, especially following welding. They maintain excellent mechanical properties, including high tensile and yield strength, along with good creep resistance, particularly in the 347H grade which is designed for sustained high-temperature service. This makes them a robust choice where both durability and heat resistance are non-negotiable.
