Fatigue strength: MS1 steel (Vxx/Snn)

This page presents the S-N curves and fatigue limit of MS1 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
Run-out criterion 107 cycles
AM layers normal to axis of rotation

Wöhler curve

Fatigue limit (MPa) 430
Number of cycles to failure N N=1,12⋅1039⋅S-12,20
Stress amplitude S (MPa) S=1592⋅N-0,082

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.
