17-4PH is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring
high strength and a moderate level of corrosion resistance.
High strength is maintained to approximately 600°F (316°C).
17-4PH stainless alloy is martensitic in structure in the annealed condition and is further
strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy.
In comparison to many alloys in the precipitation hardening family, the S17400 alloy requires a simple heat treatment;
a one step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C)
depending on the combination of strength and toughness desired.
A wide range of properties can be produced by this one step heat treatment.
Heat treatment in the 900°F (482°C) range produces highest strength.
We produce 17-4PH in sheet, strip, and plate, wire, and bar product forms.
