17-4 PH (AMS 5604)

17-4PH is chromium-nickel-copper stainless steel used for applications requiring high strength, toughness, good corrosion, and high fatigue resistance. 17-4PH is a martensitic, precipitation-hardening stainless steel. The material is fabricable and can be age-hardened in a single low-temperature heat treatment. Corrosion resistance is the best of all standard hardenable stainless steels, performing similarly to Type Type 304 in most environments. Due to the hardness of the material, formability is limited, although this may be improved significantly if the material is heat-treated before cold-working or hot-forming.

Versatility

17-7PH is a versatile engineering material that is used to produce nuclear components, aerospace parts and military structures.
