Beschreibung
Zusammenfassung:	A mechanically alloyed composition of matter or alloy containing 30-40% chromium, 5-25% cobalt, 0.5-10% iron, 0.2-0.6% aluminum, 0.3-1.2% titanium, up to 0.15% carbon, about 0.2-1% yttria, up to about 0.3% nitrogen, the % titanium being at least about 1.4 times the % nitrogen, minor amounts of optional elements, the balance being essentially nickel. The consolidated and hot worked alloy with coarse grains produced by heat treatment at about 1300 DEG C is useful in service requiring hot strength along with extraordinary resistance to oxidation, sulfidation and hot corrosive media. Specific utilization of the alloy of the invention is contemplated in handling molten glass and in utensils adapted to be used in contact with molten glass, e.g. spinners.
