Dual-Phase Microstructure · Exceptional Pitting & Crevice Corrosion Resistance · High Yield Strength · Global Supply
HRS Ferritic is a globally recognized name in the stainless steel and high-performance alloy industry, offering premium-quality materials sourced from valuable and certified mills worldwide. As a trusted Super Duplex 32750/32760 Sheet Supplier, Stockist and Importer, we deliver superior corrosion-resistant products meeting international standards such as ASTM, ASME, EN and DIN.
Super Duplex 32750 and 32760 Sheets are high-alloy stainless steel products with a dual-phase microstructure of approximately 50% austenite and 50% ferrite. High levels of chromium, molybdenum and nitrogen enhance resistance to pitting, crevice corrosion and chloride-induced stress corrosion cracking, enabling reliable performance in high-pressure and chemically aggressive conditions.
Each element in Super Duplex 32750/32760 contributes to its exceptional performance in harsh, aggressive environments.
