Inconel600 (N06600) nickel-based high-temperature alloy
US brand: Inconel600 (UNS N06600)
China brand: GH600/GH3600
I. Overview of Inconel600
Inconel600 is a nickel-chromium-iron-based solid solution strengthening alloy with good high-temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding process performance, and satisfactory thermal strength and high plasticity below 700°C. The alloy can be strengthened by cold working, and can also be connected by resistance welding, fusion welding or brazing. Zhuoyi Industry can supply cold-rolled thin plates, hot-rolled thick plates, strips, wires, bars, round cakes, ring billets, ring forgings, etc., which are suitable for making anti-oxidation parts that withstand low loads below 1100°C.
