1.Duplex 2205 Nuts

Duplex stainless steel nuts provide a higher strength of yield than typical austenitic stainless steel nuts. These complex SAF 2205 nuts also provide increased corrosion resistance and durability. Super duplex stainless steel 2205 nuts provide protection against crevice corrosion, pitting and numerous different types of corrosive cracking and wear. Furthermore, due to their solid heat resistance, duplex stainless steel nuts can be utilized in temperatures up to 570° F.

Alloy 2205 gets the name Duplex because it is composed of two different types of grains. 40-50% of its grain structure is austenite and 50-60% of it is ferrite. It is closely related to, but much more popular than Alloy 255. In most environments, it surpasses 317L in crevice corrosion resistance. Alloy 2205 excels in chloride environments and resists hydrogen sulfide. Alloy 2205 has almost twice the strength of 316L. Due to the lower nickel and molybdenum content, it is less costly than Alloy C276. Among the places where Alloy 2205 is used include pressure vessels, heat exchangers and scrubbing systems.
