17-4PH per AMS 5604
17-4PH, as specified by AMS 5604, is a martensitic precipitation hardening stainless steel specification used for solution heat treated sheet, strip, and plate products. The alloy is characterized by its combination of high strength, hardness, and corrosion resistance, which is required for applications in the aerospace, medical, and industrial sectors.
Composition and Heat Treatment
AMS 5604 is martensitic in structure and derives its properties through a single-step precipitation hardening heat treatment between 900°F and 1150°F (482°C and 621°C). This allows you to vary the properties of the alloy for specific uses, creating a broad range of properties.
Applications
17-4PH per AMS 5604 is commonly used in:
- Aerospace components such as structural parts and fasteners
- Medical devices requiring biocompatibility and durability
- Industrial equipment exposed to corrosive conditions
