    25.2.2.4 Duplex Stainless Steels. Duplex stainless steels are high alloy. The two most commonly specified grades of duplex stainless steels are UNS S31803 (with 22% Cr, 5% Ni) and UNS S32750 (25% Cr, 7% Ni). The 25% Cr material is sometimes referred to as "super duplex" or high-performance duplex.
