Type 304 stainless steel is nitrided in a 1000 deg F sodium system covered with nitrogen gas. Observations were made using a flowing-sodium loop. The degree of nitriding is heaviest at the interface between the sodium and nitrogen. The nitriding process strengthens the type 304 stainless steel at elevated temperatures and produces a marked decrease in its ductility. The stress-rupture life is greatly decreased at 1000 deg F because of nitriding. At a deflection of 0.076 in. producing a stress of 36,000 psi, the flexural fatigue life is significantly increased by nitriding. (auth)
