1 The solution nitriding process, SolNitÂ®, is performed in the austenitic phase of steel. At temperatures above 1922Â°F (1050Â°C), the thermal dissociation of nitrogen can be used to transfer into and solve nitrogen in stainless steels.  Nitrogen case depth up to .1 inches (2.5 mm) can be reached in 24 hours.
