Stainless Steel 321 Flanges are titanium-stabilized austenitic stainless steel alloys designed for high-temperature and corrosion-resistant applications. The typical composition includes C (≤0.08%), Cr (17–19%), Ni (9–12%), Ti (≥5×C%), Mn (≤2%), Si (≤1%), and Fe (balance). These flanges exhibit excellent mechanical properties, with a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%. Stainless Steel 321 offers superior resistance to intergranular corrosion, oxidation, and scaling, making it ideal for use in heat exchangers and high-temperature piping systems.
