Xuan Nickel Alloys stands out as a leading manufacturer and supplier of Duplex Steel Bolts in Da Nang, Vietnam, providing top-notch fastening solutions tailored for high-performance industrial applications. Our Duplex Steel Bolts are highly regarded for their remarkable strength, impressive resistance to corrosion, and exceptional durability in tough environments. Crafted in line with international quality standards, these bolts ensure outstanding dimensional accuracy, reliability, and performance even in extreme conditions. We cater to a diverse array of industries, including oil and gas, petrochemical, marine, chemical processing, construction, and power generation, all with our precisely engineered Duplex Steel Bolts.
These Duplex Steel Bolts are made up of 22–25% chromium, 4–7% nickel, 3–4% molybdenum, and nitrogen, which creates a well-balanced microstructure of austenite and ferrite. They deliver superior tensile and yield strength, enhanced hardness, and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. Additionally, they boast good fatigue strength, impact toughness, and weldability, making them perfect for fastening components in critical industrial settings that require high mechanical reliability and corrosion resistance.
