Fatigue strength: MS1 steel (Vxx/STn)
This page presents the S-N curves and fatigue limit of MS1 steel samples that underwent shot-peening and heat treatment (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 | shot-peening → heat treatment |
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) | 471 |
|---|---|
| Number of cycles to failure N | N=1,41⋅1050⋅S-16,39 |
| Stress amplitude S (MPa) | S=1146⋅N-0,061 |
Explanation of the terms are given at the page Fatigue strength description.
