HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
