Fatigue strength: PH1 steel (Vxx/Snn)

This page presents the S-N curves and fatigue limit of PH1 steel samples that underwent shot-peening only, obtained using the bending tests of rotating bars with AM layers normal to the axis of rotation.

Production and prost-processing conditions

Build orientation of longitudinal axis vertical
Position with respect to inert gas flow undefined
Post-processing shot-peening

Experimental S-N curve

Experimental method ISO1143, rotating bending test R=-1
AM layers normal to axis of rotation

Wöhler curve

Fatigue limit (MPa) 217
Number of cycles to failure N N=7,34⋅1013⋅S-3,41
Stress amplitude S (MPa) S=11553⋅N-0,293

Explanation of the terms are given at the page Fatigue strength description.

This page is a part of the section DMLS/SLM: Fatigue design rules.
