Xuan Nickel Alloys is a well-established manufacturer and supplier of Inconel 625 stud bolts, based in Da Nang, Vietnam, that caters to high-demanding markets like oil and gas, chemical processing, marine, and power generation. Reputable for delivering top-grade nickel alloy fasteners, Xuan Nickel Alloys provides stud bolts with accurate threading, fine surface finish, and better dimensional accuracy. Produced to ASTM and international standards, these stud bolts of Inconel 625 are built to operate dependably under corrosive, high-pressure, and elevated temperature conditions, making Xuan Nickel Alloys a reliable provider of mission-critical fastening solutions.
Inconel 625 is a nickel-base alloy that comprises about 58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium with excellent mechanical strength and corrosion resistance. Inconel 625 stud bolts possess tensile strength of about 827 MPa and yield strength of 414 MPa with high elongation and fatigue life. The alloy has good performance between cryogenic and 980°C and is extremely resistant to pitting, crevice corrosion, oxidation, and chloride-induced stress corrosion cracking. These characteristics make it particularly well-suited for aggressive offshore, subsea, and high-temperature service.

Inconel 625 stud bolts find extensive applications in flanged joints and pressure-containing joints in a number of demanding industries. They are used in oil and gas applications for subsea pipelines, risers, and wellhead equipment because they can withstand seawater and sour gas environments. They protect reactors, heat exchangers, and pressure vessels in chemical plants exposed to corrosive media. Power systems and marine systems also use these fasteners for long-term operation under thermal and mechanical stress. Inconel 625 stud bolts provide safe, secure, and maintenance-free connections in the most challenging service environments.
