150#-2500# Stainless Steel 347H Duplex Stainless Steel Flange
SS 347 / 347H Flanges are fabricated from austenitic stainless steel alloy including columbium and chromium. Therefore the presence of columbium helps in preventing resisting intergranular corrosion and carbide precipitation. Furthermore, it also includes tantalum content that exhibits higher creep and stress rupture. These flanges are often known from UNS S34709. These flanges comprise great corrosion resistance, smooth surface finish, and sturdy construction. These flanges have excellent weldability and formability qualities. However, these get non-magnetic in the annealed situation and can be hardened through cold working process.
