Stainless Steel Weld Neck Flanges are generally fabricated with austenitic stainless steels such as SS 304, 304L, 316, or 316L, which provide excellent corrosion and high-temperature resistance. Their chromium-rich and frequently nickel-containing composition offers excellent durability. They are mechanically characterized by high tensile strength (e.g., 515-620 MPa for 304/304L), satisfactory yield strength (205-220 MPa), and excellent impact resistance. A long tapered hub in the design gives them strength and enables good stress distribution in demanding applications.
