Duplex Steel S31803 Sheets and Plates feature a well-balanced austenitic-ferritic microstructure, enriched with chromium, nickel, molybdenum, and nitrogen. This unique composition grants them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh environments. On the mechanical side, they showcase impressive tensile and yield strength—almost double that of standard austenitic stainless steels—while also maintaining good ductility and toughness. These characteristics ensure structural integrity under high pressure, fluctuating temperatures, and aggressive chemical conditions, making them perfect for demanding industrial applications.
