17-4PH contains 16-18% chromium, 3-5% nickel, 3-5% copper, 0.07% carbon, and iron balance, along with trace elements. Precipitation hardening improves tensile strength (~1035 MPa), yield strength (~860 MPa), elongation ≥10%, and hardness up to 350 HB. It exhibits high fatigue resistance, good corrosion resistance, and excellent mechanical properties. Heat treatment allows tailoring of strength and toughness to meet application needs, making it ideal for structural and mechanical functions in demanding environments.
