2205 Duplex Stainless Steel Double End Stud
2205 duplex stainless steel double end stud is a high-performance fastening component designed for industrial applications requiring excellent corrosion resistance, high mechanical strength, and reliable threaded connections. The 2205 duplex stainless steel double end stud is manufactured from UNS S31803 / S32205 duplex stainless steel, combining the advantages of austenitic and ferritic stainless steel structures.
The 2205 duplex stainless steel double end stud provides excellent resistance to chloride corrosion, stress corrosion cracking, and general corrosion. It is widely used in chemical processing equipment, offshore systems, marine structures, petrochemical facilities, heat exchangers, and industrial machinery where standard stainless steel materials may not provide sufficient performance.
Product Overview
The 2205 duplex stainless steel double end stud is a threaded fastening component with threaded sections on both ends. It is commonly used with nuts and washers to create strong and stable connections in equipment assemblies, flange systems, and structural applications.
Compared with conventional 304 and 316 stainless steel fasteners, the 2205 duplex stainless steel double end stud offers higher yield strength and improved resistance to chloride-containing environments. Its duplex microstructure provides a balanced combination of strength, toughness, and corrosion resistance.
This product is commonly selected by engineers, equipment manufacturers, marine contractors, and industrial distributors requiring durable fastening solutions for challenging environments.
