fatigue failure, stress concentrators, endurance limit.Abstract
The causes of fatigue failure of metallurgical equipment parts are analyzed. The relationship between the effect of the quality of surface treatment of the part on the fatigue strength has been established. The influence of local stress concentrators on fatigue strength is determined. These are recommendations for increasing the fatigue strength of the finished part.
