Nitronic 32 (UNS S24100, XM-28) is a low-nickel austenitic stainless steel commonly chosen as a substitute for 304 stainless steel in cases where greater strength and comparable corrosion resistance are required. Both materials are excellent choices for basic cold-headed components. Nitronic 32 exhibits a high rate of work hardening, enabling enhanced strength while preserving ductility. Additionally, the material can undergo hot or cold working with ease, although annealing is recommended after extensive cold forming.

Nitronic 30 (UNS S20400) is an austenitic stainless steel that has been strengthened with nitrogen, making it suitable for various applications that demand excellent resistance to corrosion in aqueous environments, as well as toughness and cost-effectiveness. Compared to type 304, Nitronic 30 exhibits considerably higher strength, enabling the use of thinner gauges to achieve additional cost savings. Moreover, Nitronic 30 demonstrates rapid work hardening while maintaining its ductility, and it can be easily welded and formed.

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. The inclusion of copper in this grade significantly enhances its ability to withstand strong reducing acids, especially sulfuric acid. The high levels of nickel and molybdenum in the alloy provide excellent resistance to chloride-induced stress corrosion cracking, including issues like pitting, crevice corrosion, and stress corrosion cracking. Moreover, the austenitic structure of 904L stainless steel ensures exceptional toughness even at cryogenic temperatures. It can be easily welded and processed using standard fabrication techniques.

310MoLN (UNS S31050, W.Nr. 1.4466) is a nitrogen-containing high-alloy austenitic stainless steel renowned for its ability to stabilize and enhance the austenitic phase, without the presence of intermetallic phases like intergranular carbide precipitations. This material exhibits outstanding resistance to various forms of corrosion, including intergranular corrosion, pitting, and crevice corrosion, in environments such as ammonium carbamate and nitric acid. Moreover, 310MoLN demonstrates favorable weldability, albeit with a relatively high energy requirement and moderate ductility. It finds extensive usage in applications demanding exceptional strength, resistance to oxidation, and protection against chloride-induced stress corrosion cracking.

254SMO (UNS S31254, W.Nr. 1.4547) is a super austenitic stainless steel known for its exceptional corrosion resistance. It combines chromium, nickel, molybdenum, and nitrogen to provide excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. With twice the strength of stainless steel 300 series, 254SMO is often referred to as "6% Moly" due to its molybdenum content. It can withstand high temperatures and volatile conditions while offering cost-effective advantages over high nickel and titanium alloys.
