What is meant by Duplex UNS S32205 Bolts?

Steel bolts with chromium, nickel, molybdenum, and nitrogen are called Duplex 2205 (UNS S32205) Bolts. UNS S32205 bolts have excellent corrosion resistance and strength at temperatures up to 316°C. The UNS S32205 Hex bolt is regarded as one of the strongest. Duplex UNS S32205 Hex Head Bolts are the type of duplex steel bolt utilized most.

Due to the dual crystallization of its microstructure, duplex-grade steel S32205 Allen Bolts have improved characteristics. Austenite and ferrite each make up 50% of the bolts microstructure in an annealed state. Thus, both crystalline metals features coexist in the alloy of a Duplex steel UNS S32205 Bolts.

Properties of duplex UNS S32205 Bolts:

  • Like many other duplex steel grades, duplex UNS S32205 Stud Bolts have good solid temperature oxidation resistance; nonetheless, even brief exposure to temperatures above 300 degrees Celsius can cause embrittlement.   
  • Due to the ductile to brittle transition, duplex bolts are often unsuitable for use at ranges over 300 degrees Celsius or below -50 degrees Celsius due to the condensation of brittle micro components.   
  • Industries may only fix bolts made of duplex UNS S32205 if they undergo a thorough annealing procedure, which is seldom used over 300 degrees Celsius.   
  • These Duplex UNS S32205 Hex nuts, which cannot be further toughened by thermal treatment, must be heated to 1020 degrees Celsius to 1100 degrees Celsius and then swiftly cooled. ASTM A479 Duplex S32205 bolts have nearly double the strength of austenitic steel Type 304.   
  • Duplex UNS S32205 bolts are employed in various applications because of their enhanced corrosion durability and high strength. The Grade S32205 Heavy Hex Nuts protect anti-corrosion from organic compounds like acetic and formic acids. Furthermore, they grant immunity against inorganic acids that contain chloride. 
  • Additionally, non-permanent couplings may be easily and without causing any harm to the linking components made using S32205 Duplex Threaded Rods. Additionally, they offer resistance to stress corrosion cracking, particularly in chloride-containing work conditions.  
  • This fastener provides exceptional strength at a nominal temperature, even below zero. The temperature range for the stress-relieving procedure is 525°C to 600°C. This procedure helps to increase resistance in challenging conditions.
