2205 Stud Bolt, ASME SA 479 UNS S32205 Stud Bolts,UNS S31803 Stud bolt, 1.4462 Duplex Stainless steel bolt,2205 hex bolt,2205 stud bolts
2205 is a duplex stainless steel with nearly equal proportions of austenite and ferrite when properly heat treated. This microstructure makes it much more resistant to stress corrosion cracking than stainless steel 304 and 316L. 2205’s higher chromium, molybdenum and nitrogen contents give it significantly improved pitting and crevice corrosion resistance in the presence of chlorides. Its yield strength is about twice that of austenitic stainless steels. It is highly suitable for Applications in environments containing chlorides and hydrogen sulfide such as marine applications and oil and gas production.
Applications:
Oil and gas industry piping, tubing and heat exchangers; pulp and paper industry bleaching equipment, liquor tanks and digesters; cargo tanks for ships and trucks; chemical processing industry pressure vessels, tanks, piping and heat exchangers; and food processing equipment.

2205 Duplex Hex Bolt Material Benefits
UNS S32205 hex bolts (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 certain environmental rigors that other metals cannot such as corrosion, cracking, erosion, pitting and more. Stainless steel duplex 2205 hex bolts also provide twice the mechanical strength compared to standard stainless steel. Some of the additional characteristics of duplex 2205, include:
- Useful up to 600°F
- High resistance to chloride stress corrosion cracking
- Excellent corrosion resistance
- High strength
- Good sulfide stress corrosion resistance
- And more
