Conclusions 1. For samples treated in dry dissociated ammonia, as compared with samples treated in gas with a given moisture content, the nitrided case was deeper and the concentration of nitrogen in the case higher. 2. Samples treated in dry dissociated ammonia are carburized to a depth of 0.085 mm; samples treated under controlled saturation conditions are not carburized. 3. After treatment in dry dissociated ammonia the samples failed intercrystalline corrosion tests (GOST 6032-58)-the depth of attack in grain boundaries was 0.030 mm, with substantial etching of the grains over the entire surface of the microsection. The attack covered the entire carburized zone. 4. Samples treated under controlled saturation conditions were not subject to intercrystalline corrosion.
