A nickel base alloy for high temperature thermal processing hardware
requiring ultra-low spallation and metal loss rates in oxidizing and
nitriding atmospheres for use in wire mesh belting, thermocouple
sheathing, resistive heating elements, heat sensing cables, furnace
internals and like hardware. The compositional range of the alloy is
15.0-23.0 % Cr, 0.5-2.0 % Si, 0.0-4.0% Mo, 0.0-1.2 % Nb, 0.0-3.0 % Fe,
0.0-0.5 % Ti, 0.0-0.5 % Al, 0.0-0.3 % Mn, 0.0-0.1 % Zr, 0.0-0.06 % Ce,
0.005-0.025 % Mg, 0.0005-0.005 % B, 0.005-0.3 % C, 0.0-20.0 % Co, balance
Ni. The alloy possesses a high degree of hot and cold workability, phase
stability and strength retention at elevated temperatures.
