Stainless Steel 321/321H Heat Exchanger Tubing is an austenitic stainless steel alloy that contains about 17–19% chromium, 9–13% nickel, and is stabilized with titanium. The 321H variant has a higher carbon content, which enhances its strength at elevated temperatures. These alloys are known for their excellent resistance to intergranular corrosion, oxidation, and scaling, even under high temperatures. They also 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 this tubing perfect for high-temperature, high-pressure, and corrosive environments.
