The composition of Stainless Steel 321H Seamless Pipes includes chromium (17–19%), nickel (9–12%), and titanium (at least five times the carbon content), featuring a higher carbon content than standard 321 to enhance high-temperature strength. Their mechanical properties boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, along with excellent elongation and toughness. The titanium stabilization helps reduce carbide precipitation during welding, while the increased carbon content enhances creep strength and structural stability, ensuring they perform reliably under extreme heat and pressure.
