Applications Of Duplex Steel S32205 Bolt

Duplex Steel S32205 Bolts are used in the transportation, chemical, and water treatment industries. They are characterized by excellent corrosion resistance and flexibility. Typically, these bolts are used in high-temperature applications. However, there are some limitations to using them in low-temperature applications. 

Duplex Steel UNS S32205 bolts are frequently used for extreme conditions. They are also used in the oil well tool industry. Chemical storage and transport, petrochemicals, and nuclear reactors are common industries where Duplex Steel UNS S32205 Fasteners are employed.

Some Duplex Steel S32205 fasteners are manufactured by ASTM A182 and ASME B18.5 standards. These fasteners are available in various types and sizes. In addition to these, the material is also available in studs.

This metal is used in the chemical industry for bleaching equipment and pulp and paper machinery. It also provides excellent strength. It is also used in many high-temperature applications, such as heat exchangers.

Features of Duplex Steel S32205 Bolt

  • Duplex Steel UNS S32205 Material have several benefits over other stainless steel alloys. In particular, this fastener offers enhanced resistance to stress corrosion cracking. These advantages are especially advantageous when the alloy is exposed to salt water. However, these fasteners are not appropriate for temperatures greater than 300 degrees Celsius.
  • A combination of austenitic and ferritic microstructures characterizes this alloy. It has high yield and fatigue strength and is used in many applications where flexibility and toughness are required.
  • The high chromium content makes it resistant to chloride and organic acids. It is also highly resistant to carbide-related intergranular corrosion. At high temperatures, it is susceptible to embrittlement. Nevertheless, this material is age hardenable. Therefore, it is commonly used in applications such as marine environments.
  • In addition, the Duplex 2205 grade is a significant upgrade over 316 stainless steel in yield strength. It can have a tensile strength almost twice that of a comparable 304 grade.

Advantages of Duplex Steel S32205 Bolt Material

  • These Duplex Steel S32205 bolts are widely used for different industrial applications. It provides excellent corrosion resistance and is highly demanded in various markets. They offer protection against organic acids, chloride, and stress corrosion cracking. This grade of stainless steel is a combination of austenitic and ferritic alloys.
  • Generally, duplex UNS S32205 bolts are usually used in applications with high temperatures. They have an optimum temperature range from 300 to 1000 degrees Celsius. However, the rate of deformation is reduced at lower temperatures.
  • Duplex 2205 is an alloy composed of nearly equal amounts of austenite and ferrite. The dual microstructure improves the properties of the alloy. In addition, it enhances the toughness of the bolts.
  • Another benefit of this type of bolt is the low molybdenum content. The nickel, nitrogen, and carbon content also helps prevent fatigue corrosion. These metals also can resist intergranular corrosion.
  • Also, the UNS S32205 is its excellent resistance to oxidation scaling. It has good resistance to crevice corrosion, especially at high temperatures. Therefore, it is often used in marine systems.
  • In addition, duplex steel S32205 bolts material offer exceptional resistance to inorganic acids. This material is used in bleaching equipment and pulp and paper equipment.
