17-4 - UNS S17400:
Type 17-4 is the most common grade of martensitic precipitation
hardenable (PH) alloys. 17-4 provides an outstanding combination of
high strength, good mechanical properties at temperatures up to
600°F (316°C), and short-duration, low-temperature heat treatments
that minimize warpage and scaling. Its good corrosion resistance,
formability and weldability make it ideal for a variety of
applications in aerospace, petrochemical, and other structural
applications. In the annealed condition 17-4 maintains high
mechanical properties making some forming operations difficult.
Physical Properties:
- Melting Point: 2560 - 2625°F (1404 – 1440°C)
- Density: 0.282 lbs/in3 / 7.8 g/cm3

- Copper: 3.00 - 5.00
- Iron: Balance
Heat Treatments:
17-4 is typically supplied in Condition A, and can be heat treated
at a variety of temperatures and times to achieve a wide range of
properties. Below is a sampling of standard heat treatments for
Condition A 17-4 material:
| Condition | Heat To (+/- 15°F / 8.4°C) | Time at Temperature (h) |
|---|
| H900 | 900°F / 482°C | 1 |
| H1025 | 1025°F / 551°C | 4 |
| H1075 | 1075°F / 580°C | 4 |
Corrosion Resistance:
Type 17-4 PH stainless steel withstands corrosive attack better
than any of the standard hardenable (martensitic) stainless steels
and is comparable to Type 304 in most media. The alloy exposed to
seacoast atmosphere will gradually develop overall light rusting
and pitting in all heat-treated conditions. In common with other
stainless steels, 17-4 material is subject to crevice attack if
exposed to stagnant seawater for any length of time.
