HIGH NICKEL-CHROMIUM ALLOY

A high-nickel-chromium iron alloy containing aluminum and titanium is particularly useful under high temperature/oxidizing conditions such as encountered in ceramic tile industry frit-firing applications. The alloy also contains a special percentage of nitrogen as well as zirconium. The alloy composition is about 19 to 28% chromium, about 55 to 75% nickel, about 0.75 to 2% aluminum, up to about 1% titanium, zirconium in a small but effective amount sufficient to facilitate the manufacturing process and up to about 0.5%, up to 1% each of silicon, molybdenum, manganese and niobium, up to about 0.1% carbon, a small but effective amount of nitrogen sufficient to combine with the zirconium to effect grain size control and up to about 0.1%, up to about 0.2% yttrium, with the balance being iron.
