The Stainless Steel 321H Flanges from Emilio Stainless are crafted from titanium-stabilized austenitic stainless steel, featuring a higher carbon content that enhances strength at elevated temperatures. Typically, the composition includes 17–19% chromium, 9–12% nickel, along with added titanium and increased carbon levels to boost creep resistance. These flanges boast a minimum tensile strength of about 515 MPa and a yield strength of 205 MPa. Their mechanical properties provide excellent stability at high temperatures, along with resistance to oxidation and intergranular corrosion. Stainless Steel 321H is particularly effective for pressure-containing components that operate under significant thermal stress.
