17-4 PH stainless steel machining is a balancing act between a martensitic precipitation-hardening alloy’s strength and its post-heat-treatment growth. 17-4 PH (UNS S17400) reaches roughly 40-45 HRC after aging, yet machines reasonably in the solution-treated condition. The catch is that aging changes dimensions slightly, so a 17-4 PH stainless steel machining plan must decide what […]
