Duplex steel UNS S32205 bolts are one of the most highly demanded products in industries today. These bolts are known for their effective and efficient nature. Duplex Steel UNS S32205 is considered the most sturdy and robust grade. These bolts are generally used for extreme conditions and high temperatures.
Duplex steel UNS S32205 grade is considered one of the most sturdy grades. The most frequently used Duplex(ferritic/austenitic) stainless steel grade is duplex UNS S32205 Hex Head Bolts. Although duplex UNS S32205 has high solid temperature oxidation resistance, like other duplex stainless steel grades, it is susceptible to embrittlement when exposed to temperatures exceeding 300 degrees celsius for even short periods. Because of its ductile to brittle transition, duplex bolts are not typically appropriate for usage at temperatures over 300 degrees celsius due to precipitation of brittle micro components nor below -50 degrees celsius.
If duplex UNS S32205 bolts become brittle, they can only be repaired with a complete annealing process which is never really utilized over 300 degrees celsius. Solution treatment (annealing) - heat these duplex UNS S32205 bolts to 1020 degrees celsius - 1100 degrees celsius and cool quickly, which cannot be hardened further by thermal treatment. The strength of duplex UNS S32205 bolts is roughly double that of Type 304 austenitic stainless steel. Because of its outstanding corrosion resistance and high strength, duplex UNS S32205 bolts are used in various applications. The duplex UNS S32205 bolts also provide corrosion protection from organic acids such as acetic acids and formic acids. They also offer protection from inorganic acids that contain chloride. Due to the low carbon content in duplex UNS S32205 bolts, they are highly resistant to carbide-related intergranular corrosion. Duplex UNS S32205 bolts are also used in creating non-permanent joints, which can be dismantled on-demand with ease without causing any damage to the joining components. They also provide resistance towards stress corrosion cracking, especially in work chloride environments.
