Stainless Steel 321 and 321H Instrumentation Tubing are austenitic stainless steels that contain about 17–19% chromium, 9–13% nickel, and are stabilized with titanium. The 321H variant has a higher carbon content, which enhances its high-temperature strength. These alloys are known for their excellent resistance to intergranular corrosion, oxidation, and scaling at elevated temperatures. On the mechanical side, they boast high tensile strength, good toughness, and dimensional stability, all while maintaining ductility and formability. The titanium stabilization not only improves weldability but also prevents sensitization during heating, making 321 and 321H Instrumentation Tubing perfect for high-pressure, high-temperature, and corrosive environments.
