Carbo-Nitriding

Syracuse Heat Treating is NADCAP Certified for this process. We have four Endothermic Atmosphere, Integral Quench Carbonitriding furnaces. Working dimensions: 32" x 48" x 30"

Carbonitriding is a heat treatment process in which a low carbon steel absorbs carbon and nitrogen generated by an endothermic atmosphere mixed with natural gas and ammonia into its surface to a specific depth determined by time and temperature followed by quenching to achieve desired properties.  Case depths from as little as 0.002" to as deep as 0.125" may be specified, depending on the service requirements of the product, although specified case depths beyond 0.030" are uncommon. Carbonitriding is one of the most widely used surface hardening process for low alloy, low carbon steels.
