The inherent strength of our Stainless Steel 347/347H EFW pipes begins with their composition, which is stabilized with niobium. This crucial addition grants them exceptional resistance to sensitization and intergranular corrosion, particularly following exposure to high temperatures. The result is a material that maintains its integrity and superior mechanical properties, including impressive tensile strength and excellent creep resistance, under sustained stress and elevated temperatures, making it a fundamentally robust choice for the most challenging environments.
