At Nascent Pipe & Tubes, we take pride in being a leading manufacturer and exporter of high-performance A286 Tubes that meet the highest global standards. Known by its universal designation as UNS S66286, Alloy A286 is an iron-nickel-chromium-based austenitic stainless steel designed for applications requiring excellent strength and oxidation resistance at elevated temperatures up to 704°C (1300°F). These tubes are produced in accordance with the ASTM A453 Grade 660 specification, ensuring reliable mechanical properties and heat-resistance performance.

Our A286 Tubes are widely used in demanding environments such as aircraft engines, turbines, exhaust systems, power generation plants, offshore drilling, and chemical processing. These tubes offer excellent fabrication and welding characteristics while retaining good ductility after aging. At Nascent Pipe & Tubes, our manufacturing process follows stringent quality protocols to ensure every tube maintains exceptional tensile strength, stress rupture resistance, and corrosion resistance in aggressive environments.
