321/321H Stainless Steel is an austenitic stainless steel grade containing titanium stabilizing to avoid precipitation of carbides. Its chemical composition contains approximately 17-19% chromium, 9-12% nickel, and around 0.5% titanium, while the 321H grade contains greater carbon content for enhanced high-temperature properties. This seamless tubing is characterized by superior mechanical properties like tensile strength of about 515 MPa, good yield strength, and a higher resistance to corrosion and oxidation. It is an ideal choice for applications in high temperatures because of its greater creep rupture strength.
