A Super duplex is a microstructure with 50% austenite and 50% ferrite. Due to the combination of these two, the grade strength had been increased. Super duplex is almost the same as duplex steel, but the only dissimilarity between these two is that duplex steel contains 22% of chromium, and super duplex steel contains 25% of chromium. Due to chromium's availability, the steel's hardness increases and the corrosion resistivity also improves. Hence the addition of a few more percent of chromium is always advantageous.

UNS S32550 Super Duplex Screws have high resistance to pitting corrosion and a chloride-rich environment. They have higher copper levels, lower nickel, and no deliberate tungsten additions. Therefore, unique strength and chloride stress corrosion cracking resistance combinations are developed. They are preferred while welding heavy parts.
