This High Strength Stud strictly follows the ANSI B18.31.1M standard and has a specification of M24 x 250 mm. This stud bolt is manufactured using high-quality 2205 duplex stainless steel combined with a property class of 10.9 high strength, offering excellent tensile strength and outstanding corrosion fatigue life. Its outstanding high yield strength and durable characteristics make this High Strength Stud an ideal fastening solution for high-pressure valves, flange connections, and piping systems under harsh operating conditions.
2205 duplex stainless steel is an alloy material consisting of a two-phase microstructure of austenite and ferrite, with the two phases accounting for approximately 50% each.
1. Extremely high yield strength
The yield strength of 2205 is approximately 450 MPa or more, which is more than twice that of ordinary 304 stainless steel (approximately 205 MPa).
This means that for an M24 High Strength Stud, using 2205 material can withstand higher pre-tightening force, making it less prone to thread plastic deformation or galling.

2. Resistance to chloride-induced stress corrosion cracking
Ordinary 316 stainless steel is prone to sudden brittle fracture due to stress corrosion cracking in chloride-containing environments (seawater, salt spray, chemical media).
Performance of 2205: Its ferrite phase can effectively prevent crack propagation, making it particularly suitable for High Strength Stud applications in offshore platforms, seawater desalination, and chemical pipeline flange connections.
