Product Name: Precipitation‑Hardened (PH) Steel Plate
Introduction
Precipitation‑Hardened (PH) Steel Plate is a corrosion‑resistant, high‑strength alloy that achieves exceptional mechanical properties through precipitation of fine intermetallic particles after solution annealing and aging. Commonly based on chromium, nickel, copper, and aluminum chemistries, PH steels combine weldability and toughness with yield strengths up to 1,300 MPa. These plates are ideal for aerospace fittings, high‑pressure hydraulic components, and superplastic forming applications where lightweight strength and dimensional stability are critical.

Features & Advantages
Ultra‑High Strength: Aging treatments precipitate copper‑rich phases to boost yield strength up to 1.3 GPa.
Good Corrosion Resistance: Chromium and nickel content affords resistance in mild seawater and many chemical environments.
Excellent Dimensional Stability: Minimal distortion during aging ensures tight geometric tolerances.
Weldability & Fabrication: Grades like 17‑4PH can be welded in solution‑annealed condition and subsequently aged for full strength.
Elevated Temperature Performance: Maintains strength and creep resistance up to 315 °C, suitable for aerospace and turbocharger components.
Applications
Aerospace & Defense: Fittings, actuators, and structural brackets requiring high strength‑to‑weight ratios.
Oil & Gas: Downhole tools, valve components, and high‑pressure fittings.
Marine: Propeller shafts, coupling hubs, and pump impellers.
Industrial Machinery: Hydraulic actuator rods, fasteners, and wear‑resistant plates.
Superplastic Forming: Thin‑gauge plates for automotive and aerospace complex‑shape panels.
Packaging & Delivery
Packaging:
