Nickel-chromium-iron based casting alloy

摘要

Provided is a novel Ni-Cr-Fe-based casting alloy suitable for use in manufacturing a component for contacting molten glass, such as a centrifugal spinner for forming fibers of a molten glass by a rotary fiber forming process, for example. This Ni-Cr-Fe-based casting alloy is suitable for use in manufacturing a component for contacting molten glass, and is characterized by containing, in terms of mass percent, 15-30% Cr, 15-30% Fe, 2.5-5.0% Co, 3.0-6.0% W, 0.0-2.0% Ti, 0.5-2.5% Nb, 0.5-2.0% Mo, and 0.5-1.2% C, the remainder comprising nickel and unavoidable impurities.
