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, S31803 material can be utilized in temperatures up to 570° F.

Duplex 2205 Nuts Material Advantages

Duplex 2205 Nut

UNS S32205 nuts (also known as S31803) are manufactured from high-grade duplex 2205 stainless steel. Since this material is composed of at least 22% chromium, 6% nickel and 3% molybdenum it can withstand several unique types of environmental inflexibilities that other metals cannot such as corrosion, cracking, erosion, pitting and more. S31803 material nuts also provide twice the mechanical strength compared to standard stainless steel. Some of the additional characteristics of duplex 2205, include:

  • Useful up to 570°F
  • High resistance to chloride stress corrosion cracking
  • Excellent corrosion resistance
  • High strength
  • Good sulfide stress corrosion resistance
  • And more

In addition, Duplex 2205 is the most widely used duplex stainless steel grade on the market.  The Duplex 2205 alloy is a nitrogen-enhanced duplex stainless steel alloy. The nitrogen serves to significantly improve the corrosion resistance of the alloy; especially in the welded condition.

Duplex 2205 Nut Applications

UNS S32205 nuts (also known as S31803) are often used for standard and advanced fastening applications. The steel’s intrinsically strong characteristics make it the perfect choice for a wide variety of industrial applications. Some of which, include:

  • Engineering
  • Textile
  • Paper
  • Petrochemical
