The Stainless Steel 321/321H seamless tubing is an austenitic chromium-nickel alloy that’s stabilized with titanium, which boosts its resistance to intergranular corrosion. It typically contains 17–19% chromium, 9–12% nickel, and titanium to enhance stability at high temperatures. This tubing showcases impressive mechanical properties, with tensile strength ranging from 515–750 MPa and yield strength between 205–275 MPa, depending on the grade and heat treatment. It also boasts an elongation of 40% or more, providing flexibility without sacrificing strength. The 321H variant, with its higher carbon content, offers enhanced creep resistance, making both grades perfect for applications involving extreme temperatures and pressures.
