Fatigue performance of PH1 steel

This page presents the design rules for AM product manufactured from stainless steel PH1, which include considerations of the influences of production conditions and processing procedures to fatigue resistance of products made by that material. This page also represents the introductory page to the sections that present the S-N curves and fatigue limits of products manufactured from PH1 under different production conditions and post-processing procedures.
