Specialty alloys, as key enabling materials, address extreme environmental challenges inmodern industry and cutting-edge technologies that conventional materials cannotovercome.

High-performance Inconel and Monel ,hastelloy and duplex 2205 heavy hex bolts, stud bolts, and hex nuts ensure critical structural integrity, corrosion resistance, and safety in extreme offshore drilling and harsh subsea petroleum extraction environments.

Precision-engineered socket screws and custom machined fasteners in high-strength Duplex Stainless and Nimonic 80A maximize vehicle durability, component safety, and weight reduction across modern automotive manufacturing lines globally.

Certified Super Duplex S32750 and 904L Inconel625 flange components and specialty stud bolts deliver vital radiation resistance, exceptional durability, and maximum operational safety for critical high-pressure nuclear power generation systems.

Corrosion-resistant Hastelloy, 254SMO, and Titanium heavy hex bolts and hex nuts withstand aggressive acids and high temperatures, preventing dangerous leaks in severe industrial chemical processing and fluid handling plants.

High-temperature alloy, Titanium, and Inconel custom machined fasteners or socket screws and bolts provide the exceptional creep resistance and mechanical strength required to guarantee mission success in demanding aerospace applications.
Cooperative customer
Under the leadership of presiden Tang, our second factory "Du Xun " was build only ten minitues driving way from our old factory ,which equiped with more comprehensive range of production facility.Duxun alloy & our export branch high hope industry provide experienced service to clients.







NORSOK M-650, PED, API & SGS CERTIFIED FACTORY
Our advanced thread rolling equipment utilizes precision C-frame power presses engineered to handle extreme work-hardening. We roll high-strength threads for material such as Inconel 718 heavy hex bolts, Hastelloy C276 socket screws, and Super Duplex S32750 stud bolts to exact dimensional tolerances.
Our heavy-duty straightening machinery guarantees perfect axial alignment for elongated fasteners. This critical process ensures that such as high-temperature Nimonic 80A threaded rods, Inconel 625 studs, and custom exotic alloy bar stocks remain entirely straight under extreme industrial stress
High-precision punch press production lines utilize pneumatic stamping to manufacture uniform components quickly. We stamp resilient Inconel 625 flat washers, high-performance lock washers, and specialized Super Duplex S32750 nuts tailored for severely corrosive offshore marine or chemical environments
Our industrial hot heading equipment applies localized thermal forging to shape oversized bolt heads cleanly. This specialized capability allows us to manufacture premium Titanium socket head cap screws, Hastelloy heavy hex bolts, and non-standard custom engineered fasteners.
