NADCAP certified, Syracuse Heat Treating's Nitriding Retort is 26" dia x 36" deep. Gas nitriding is a surface hardening process, where by nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case is developed at relatively low temperatures without the need for quenching; thus, little or no distortion. Parts to be nitrided are pre-heat treated, and often stress relieved prior to final machining. As a result, a very high strength product with extremely good wear resistance can be produced.
