PURPOSE: To inexpensively obtain an alloy for the spinner producing glass fibers with excellent resistance to molten glass corrosion and large creep rupture strength at elevated temperature.
CONSTITUTION: This Ni-based heat-resistant alloy has the following composition: C, 0.2-1.2wt.%; Si, 0.5-3wt.%; Mn, 0-1wt.%; Cr, 20-35wt.%; Co, 5-30wt.%; W, 5-10wt.%; one or two of Nb and Ta, 0.5-3wt.%; Fe, 5-20wt.%; and the rest (preferably 20-30wt.%) of Ni and unavoidable impurities. If necessary, one or two of W and Mo, 5-15wt.%; one or two of Ti and Zr; 0.3-1wt.%; and one, two or more selected from the group consisting of Ce, 0.02-1wt.%, Al, 0.5-3wt.% and B, 0.001-0.5wt.% are also used to give a heat-resistant alloy of the similar level of performance.
