Carbonitriding is a modification of gas carburizing in which a small amount of nitrogen is diffused into the steel surface along with carbon. Carbonitriding is carried out at a slightly lower temperature and for a shorter time than gas carburizing. It is used primarily for plain low carbon steels that would not respond to standard carburizing. Carbonitriding is limited to shallow case depths (<0.015").
NATIONAL HEAT TREAT can perform carbonitriding in any of our five atmosphere furnaces.
