ABSTRACT:
A casting alloy consisting essentially of 20 to 40% chromium, 2 to 12% molybdenum, up to 2% silicon, up to 5% manganese, up to 1% carbon, 0.1 to 1% nitrogen, and the remainder cobalt and the usual impurities inherent to the manufacturing process. The alloy is subjected to a heat treatment to homogenize the lattice of the alloy, and thereafter the alloy is rapidly quenched in order to prevent reformation of deposits in the lattice.
