The Stainless Steel 321H Tubing is made from chromium-nickel austenitic stainless steel that’s stabilized with titanium and features a higher carbon content compared to SS 321. This unique composition boosts its high-temperature strength and helps prevent carbide precipitation. The tubing boasts excellent mechanical properties, including high tensile and yield strength, good creep resistance, and remarkable toughness, even when exposed to elevated temperatures for extended periods. It also excels in oxidation resistance and structural stability, making it a perfect fit for thermal cycling and high-pressure environments.
