15-5PH AMS 5659
15-5 PH AMS 5659 stainless steel is a martensitic precipitation-hardening stainless steel which maintains a high strength to approximately 600 °F. Compared to 17-4 PH, it offers better transverse toughness and ductility: better mechanical properties in larger cross-sections, and better forgeability.
