The strength of this tubing comes from its specific composition. It’s an austenitic chromium-nickel steel enhanced with titanium, which grants it superior resistance to corrosion and oxidation, particularly in high-temperature settings. This stability allows it to maintain excellent mechanical properties, including high tensile strength and good ductility, even when subjected to intense heat, making it a fundamentally sturdy and dependable material for engineers and fabricators.
