Effect of mechanical treatment on the strength of austenitic steel

1. The surface treatment has a considerable effect on the fatigue limit of steel 25Kh13G18NAF1.5 —surface plastic deformation increases the fatigue limit of smooth samples by 70% and the fatigue limit of notched samples more than 200%. 2. Nitriding is also an effective method of increasing the fatigue limit of steel 25Kh13G18NAF1.5, raising it more than 100%.
