The Super Duplex Steel Slitting Coils from Tanvir Nickel Alloys are generally produced using UNS S32750 and S32760 grades. These alloys boast around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, resulting in a dual-phase microstructure that merges the advantages of austenitic and ferritic stainless steels. This combination leads to remarkable resistance against pitting, crevice corrosion, and stress corrosion cracking, even in harsh, chloride-rich chemical environments. On the mechanical side, these coils deliver high yield and tensile strength—up to 800 MPa—making them perfect for applications that demand durability, pressure resistance, and long-lasting structural integrity.
