2507 Duplex Stainless Steel Double End Stud Bolt
2507 duplex stainless steel double end stud bolt is a high-performance fastening component designed for applications requiring excellent corrosion resistance, high mechanical strength, and reliable connection performance. The 2507 duplex stainless steel double end stud bolt is manufactured from super duplex stainless steel UNS S32750, combining the advantages of austenitic and ferritic stainless steel structures.
The 2507 duplex stainless steel double end stud bolt provides outstanding resistance to chloride corrosion, pitting, and stress corrosion cracking. It is widely used in offshore engineering, petrochemical equipment, marine systems, chemical processing plants, desalination equipment, and heavy industrial applications where standard stainless steel fasteners cannot meet environmental requirements.
Product Overview
The 2507 duplex stainless steel double end stud bolt is a threaded fastening component with threads on both ends and an unthreaded center section. It is commonly installed with nuts for flange connections, pressure equipment, and structural assemblies requiring strong and corrosion-resistant fastening.
Compared with 304 and 316 stainless steel fasteners, the 2507 duplex stainless steel double end stud bolt offers higher strength and improved resistance to chloride-containing environments. Its duplex metallurgical structure provides excellent mechanical properties while maintaining good corrosion resistance.
This product is commonly selected by engineering contractors, equipment manufacturers, marine system builders, and industrial distributors for demanding applications.
