Fatigue data for laser beam powder bed fused 17-4 PH stainless steel specimens in different heat treatment and surface roughness conditions.

ABSTRACT: This article presents the data demonstrating the synergistic effect of surface roughness and heat treatment on the fatigue behavior of 17-4 PH stainless steel (SS) fabricated via laser beam powder bed fusion (LB-PBF) [1]. Two sets of specimens, in as-built and machined surface conditions, were heat treated using five different recommended procedures for 17-4 PH SS by ASTM A693. Axial fully-reversed fatigue tests (R = -1) were conducted on heat treated as-built and machined specimens. The stable hysteresis stress-strain data, as well as the maximum and minimum stress and strain values for the cycle in a log10 increment are included for all conducted fatigue experiments. In addition, fractography images are provided for selected set of specimens.
