Nitridation Resistance

HAYNES^® HR-160^® alloy is also very resistant to nitridation attack. Tests were performed in flowing ammonia or nitrogen at various temperatures for 168 hours. Nitrogen absorption was determined by chemical analysis of samples before and after exposure and knowledge of the exposed specimen area.
