Abstract

Procedure for nitriding ferrous pieces, which includes placing the ferrous pieces in an oven and heating them to a temperature of the order of 1000ºF to 1200ºF, characterized by the fact of introducing an atmosphere into the furnace that comprises, by volume, 5 to 25 percent ammonia, 3 to 4 percent hydrogen, and the rest of the atmosphere is a carrier gas.
