Fatigue strength: MS1 steel (VDx/TMS)
This page presents the S-N curves and fatigue limit of MS1 steel samples produced in the part of the production chamber near the outlet of the inert gas flow, then post-processed by heat treatment, machining that removed allowance of 0.5mm and shot-peening (in that order). The fatigue data were obtained using the bending tests of rotating bars with AM layers normal to the axis of rotation.
