Welcome to Salem Stainless Steel Suppliers Pvt. Ltd., your premier destination for high-strength, corrosion-resistant piping solutions. In modern industrial environments, standard stainless steels often face limitations in high-chloride and high-stress conditions. To overcome these challenges, we offer Stainless Steel Duplex 2205 Flanges — the most widely used duplex grade in the industry.

SS Duplex 2205 Flanges are forged duplex stainless steel components designed to ensure secure, leak-proof connections in piping systems exposed to chlorides, acids, and high mechanical loads. With a balanced 50/50 austenite-ferrite microstructure, these flanges provide exceptional pitting resistance, superior stress corrosion cracking resistance, and high mechanical strength—making them ideal for demanding offshore, chemical, and marine environments.
