Key Properties of 17-4PH Stainless Steel
High Strength & Hardness
– Achieves up to 1300 MPa (190 ksi) tensile strength after aging
Excellent Corrosion Resistance
– Comparable to Type 304 stainless steel in most environments
Good Fabricability
– Can be machined, welded, and formed with proper heat treatment
Precipitation-Hardenable
– Strengthened via single-step low-temperature aging (H900, H1025, etc.)

Applications of 17-4PH Stainless Steel
Due to its superior mechanical properties and corrosion resistance, 17-4PH is used in:
- Aerospace – Turbine blades, structural components
- Oil & Gas – Valves, pump shafts, downhole tools
- Medical – Surgical instruments, orthopedic implants
- Chemical Processing – Pressure vessels, reactor parts
- Marine – Shafts, fasteners, propeller fittings
- Industrial – Gears, molds, high-strength fasteners
Heat Treatment & Aging Options
17-4PH is typically supplied in Solution Annealed (Condition A) form and can be strengthened via precipitation hardening:
- H900 – Peak hardness (HRC 40-45), high strength
- H1025 & H1075 – Balanced strength & toughness
- H1150 & H1150M – Improved corrosion resistance & stress corrosion cracking (SCC) resistance
- Proper heat treatment ensures optimal mechanical properties for specific applications.
Machining & Forming Considerations
Machinability – Best performed in annealed condition; carbide tools recommended
Formability – Limited in hardened state; hot forming or pre-annealing improves workability
Welding – Possible with post-weld heat treatment to restore properties
