Summary of the primary material characteristics identified in this study

Material	Main characteristics
17-4PH Hard tool steel AISI 630	Part of the original internal lattice structure remains (large porosity) External and internal areas have different metallographic structures Material resistance is consistent across parts within batches Surface hardness is uniform across parts, batches and specimen position
H-13 High resistance hot work steel AISI H13	Completely sintered parts with just a small internal cavity Homogeneous grain structure across the whole section Very high resistance with low variability across parts Extremely high surface hardness Unexpected hardness variability within specimen location and sintering batches
