316 Stainless Steel Flange
Stainless Steel 316 Flange is a high-performance flange designed for superior corrosion resistance and durability in harsh environments. Manufactured from molybdenum-bearing austenitic stainless steel, SS316 flanges offer excellent resistance to chloride-induced pitting, crevice corrosion, and general oxidation. These flanges are widely used in chemical processing, marine applications, oil & gas pipelines, and pharmaceutical systems where high strength and hygienic standards are required. Available in various types such as weld neck, slip-on, blind, threaded, and socket weld, our 316 stainless steel flanges meet global standards including ASME B16.5, ANSI, and EN 1092-1.
Choose Stainless Steel 316 Flanges for dependable, long-lasting performance in corrosive and high-pressure systems.
