17-4PH is a well-established precipitation hardening martensitic stainless steel capable of achieving very high strength and hardness after a relatively simple heat treatment. It offers excellent corrosion resistance combined with a structured range of mechanical property levels depending on the precise heat treatment applied.
The materials can be readily machined and fabricated in the softer tempers and can then be heat-treated to exceptional strength and dimensional stability. 17-4PH is widely used in the chemical, petrochemical, offshore, paper, and aerospace industries making best use of its outstanding corrosion resistance, wear resistance, strength and hardness.
Main fields of application of 17-4PH/ AISI630
Surgical and dental instrument, screwdriver.
17- 4 retains a high strength of precipitation hardening stainless steels a majority of applications are within the aerospace sector and OAG applications
- Valves and engine components
- Turbine blades
- Gears
- Shafts
- Aircraft structures
17-4PH Stainless Steel Foil Chemical Compositions
The chemical components of grade 17-4PH stainless steel foil is summarized in the following table:
| C | Si | Mn | P | S | Cr | Ni | Cu | Nb |
| 0.07 max | 1.00 max | 1.00 max | 0.040 max | 0.030 max | 15.00~17.50 | 3.0~5.0 | 3.0~5.0 | 0.15~0.45 |
Heat treatment
Alloy 17-4PH is provided in the solution-annealed condition (Condition A). Mechanical properties may be improved by subsequent age hardening treatments. These aging treatments are commonly described as conditions H900, H1025, H1075, H1150, H1150M and H1150D.
