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
