INCONEL® alloy 601GC® is a nickel-chromium-iron alloy with additions of aluminum, zirconium and nitrogen. High levels of nickel and chromium give the alloy excellent strength and corrosion resistance at elevated temperatures. Oxidation resistance is further enhanced by the aluminum content.

INCONEL alloy 601GC is a grain-controlled version of INCONEL alloy 601 (UNS N06601). Zirconium and nitrogen in INCONEL alloy 601GC act to inhibit grain growth during exposure to high temperatures. Grain size stability is an important factor in obtaining optimum performance and service life at high temperatures.

The properties of INCONEL alloy 601GC are especially suitable for seam-welded roller tubes in roller-hearth furnaces used for the production of glazed ceramic tiles. The alloy has the strength and resistance to oxidation and corrosion needed for long, economical service in these continuous-duty tile-firing kilns.
