Alloy 2205 (SAF 2205®) Fasteners (ASTM A479/UNS S32205/Duplex F60/1.4462)
Alloy 2205 is a 22% Cr duplex stainless steel, supplied in the solution annealed condition. As a duplex stainless steel, it combines the desirable aspect of properties of both austenitic and ferritic grades. The high chromium, molybdenum and nitrogen contents results in a Pitting Resistance Equivalent number (PREN) of 33-34, providing pitting and crevice corrosion resistance superior to Alloy 316L or Alloy 317L austenitic stainless steels in almost all corrosive media. Due to its excellent corrosion properties, it is well-suited to environments containing chlorides and hydrogen sulphide, for use in oil and gas extraction from sour wells, in refineries and in process solutions contaminated with chlorides.
Duplex Fasteners including Bolts, Nuts, Socket Capscrews, Washers, Studs, Studbolts, Socket Setscrews, Socket Countersunk Screws & machined components to all recognised standards drawings as well as customer drawings can be produced at Beacon Corporation Limited.
