Product Overview

Inconel 600 (UNS N06600) and Inconel 601 (UNS N06601) are classic nickel‑chromium iron‑base super alloy seamless pipes, widely selected for high‑temperature and corrosive operating conditions. Inconel 600 provides reliable anti‑corrosion performance in both oxidizing and reducing media; Inconel 601 optimizes aluminium element addition, delivering much better high‑temperature oxidation scaling resistance.

Our Inconel 600 / 601 seamless super alloy pipes are manufactured via hot extrusion combined with cold drawing solution annealing treatment. Strict non‑destructive inspection including eddy‑current, ultrasonic test is implemented for each batch. Products are commonly applied in industrial furnace components, heat‑treatment roller, petrochemical cracking tube, heat exchanger piping, waste‑gas treatment equipment and nuclear‑industry auxiliary piping. We can produce standard stock sizes as well as non‑standard dimension per client CAD drawing, meet global industrial project procurement requirements.
