These stainless steel 321H pipes are made up of chromium (17–19%), nickel (9–13%), and titanium (0.3–0.8%), featuring a higher carbon content than standard 321 to boost high-temperature strength. This unique combination of elements grants them excellent resistance to oxidation, intergranular corrosion, and thermal fatigue. They boast impressive mechanical properties, including a tensile strength of 515–700 MPa, yield strength of 205–275 MPa, elongation of 35–40%, and hardness below 90 HRB. These characteristics ensure that the pipes are not only durable but also maintain their structural integrity and resist creep even under prolonged high-temperature conditions.
