UNS S32760 (W.Nr. 1.4410, F55) is a type of duplex stainless steel that is specifically engineered to withstand harsh environments containing chloride. It contains additional elements like tungsten (W) and copper (Cu) compared to UNS S32750. This particular steel exhibits excellent resistance to localized corrosion and stress corrosion cracking, while also possessing high mechanical strength. Due to its exceptional pitting resistance and high yield strength, S32760 enables more efficient and lightweight designs in load-bearing applications. As a result, it finds extensive usage across diverse fields.

UNS S32550 (W.Nr. 1.4507, F61) is a highly alloyed, super duplex stainless steel known for its exceptional strength, wear resistance, and superior corrosion resistance compared to 316 stainless steel. It also exhibits good ductility and high fatigue strength, surpassing alloy 20 and duplex 2205 in terms of yield strength. However, it is important to note that when exposed to temperatures between 1000°F and 1800°F, carbides, nitrides, and sigma phase can form in UNS S32550 stainless steel if soaked within that temperature range.

Super duplex 2507 (UNS S32750, W.Nr. 1.4410) offers a unique combination of high strength and outstanding corrosion resistance. It demonstrates remarkable resistance to general corrosion and localized corrosion, including pitting and crevice corrosion, particularly in demanding environments with high chloride levels and elevated temperatures. Additionally, its duplex structure provides excellent protection against stress corrosion cracking. However, it is important to note that, like other duplex (ferritic/austenitic) grades, Super duplex 2507 is not suitable for extreme temperature conditions. It is not recommended for use below -50°C or above +300°C due to concerns about potential loss of toughness.

Duplex 2205 (UNS S32250, UNS S31803, W.Nr. 1.4462) is a highly popular grade of stainless steel known for its duplex (ferritic/austenitic) structure. It offers excellent resistance to corrosion and erosion fatigue, along with lower thermal expansion and higher thermal conductivity compared to austenitic steels. The yield strength of Duplex 2205 is approximately twice that of austenitic stainless steels.This stainless steel grade is widely utilized in various applications within a temperature range of -50ºF to +3000ºF. However, it is not recommended for use at temperatures exceeding 300°C, as it may experience the precipitation of brittle micro-constituents. Likewise, it should be avoided below -50°C due to potential ductile-to-brittle transition.

904L (UNS N08904, W.Nr. 1.4539) is an austenitic stainless steel with a high alloy composition and low carbon content. It is specifically designed to offer moderate to high corrosion resistance in various process environments.
