Wai Nickel Alloys is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializing in top-notch Duplex Steel Tubing. Renowned for its impressive strength, resistance to corrosion, and long-lasting durability, the Duplex Steel Tubing from Wai Nickel Alloys is crafted to meet the rigorous demands of today’s industries. The company prides itself on precision manufacturing, strict adherence to global standards, and consistent product quality, ensuring outstanding performance even in the toughest environments. These tubes are perfect for sectors like oil and gas, chemical processing, and power generation, where reliability and longevity are absolutely essential.
Duplex Steel Tubing features a well-balanced microstructure of austenitic and ferritic stainless steels, typically comprising chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen. This distinctive composition offers a fantastic blend of high tensile strength (620–850 MPa), yield strength (around 450 MPa), and remarkable toughness. The dual-phase structure significantly boosts resistance to pitting, crevice corrosion, and stress corrosion cracking, ensuring peak performance in high-pressure and chloride-rich settings.
