FATIGUE PROPERTIES OF 17-4 PH AND 15-5 PH STEEL IN THE H-900 AND H-1050 CONDITION

Abstract

The rotating beam fatigue properties of 17-4 PH and 15-5 PH steels were evaluated for the H-900 and H-1050 conditions. In addition, the effect of shot peening on 15-5 PH was investigated. The results indicate that the two alloys behave similarly. Over aging to the H-1050 results in a 5% decrease in the endurance limit when compared to the H-900 condition. Shot peening improves the finite fatigue life by an order of magnitude.
