These pipes are made from austenitic stainless steels that contain around 17–19% chromium, 9–13% nickel, and niobium (columbium) as a stabilizer. The 347H variant has a higher carbon content, which gives it added strength at elevated temperatures. These alloys are known for their outstanding resistance to intergranular corrosion and oxidation, especially in high-temperature environments. On the mechanical side, they offer high tensile strength, good toughness, and excellent dimensional stability. The electropolishing process enhances the smoothness of the surface, reduces contaminants, and further improves corrosion resistance, making them ideal for applications where both mechanical performance and surface integrity are crucial.
