Fatigue strength: PH1 steel (Vxx/MSn)
This page presents the S-N curves and fatigue limit of PH1 steel samples that underwent machining that removed allowance of 0.5mm and shot-peening (in that order), 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 | machining allowance 0.5mm → 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) | 457 |
|---|---|
| Number of cycles to failure N | N=1,02⋅1023⋅S-6,54 |
| Stress amplitude S (MPa) | S=3312⋅N-0,153 |
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.
