All data and graphs on front page reflect values of H900 heat treated 17-4 PH SS. Markforged represent typical tested values, while MIM H900 and Wrought H900 represent typical reference values from MPIF Standard 35. For values of Markforged printed 17-4 PH SS as-sintered and with H11 SO heat treatment please see the reverse side. All composition and "As-Sintered" data verified by a third party test facility. All microstructure images etched and photographed at Markforged.
