17-4PH Stainless Steel (1150)

17 4PH H1150 stainless steel is a martensitic, precipitation-hardening alloy that combines high strength, good corrosion resistance, and excellent mechanical stability after aging at around 1150 °F (≈ 621 °C). This versatile 17 4PH material is widely used in aerospace, engineering, and industrial applications requiring strength and reliability.

Key Features

This grade provides high tensile and yield strength in the hardened condition, along with excellent wear and fatigue resistance. Its precipitation hardening capability allows fine-tuning of properties through heat treatment, making 17 4PH SS ideal for critical components where both performance and corrosion resistance are important.

Typical Applications
  • Aerospace structural components, landing gear parts, and actuator housings
  • Oil and gas valve stems, pump shafts, and high-strength marine components
  • Chemical process equipment, tooling, and shafts requiring strength and corrosion resistance
  • General engineering parts needing high strength with moderate corrosion resistance

Forms of Supply

Available in plates, round bars, sheets, wires, and forgings in solution annealed (Condition A) or precipitation hardened (H1150) condition, ready for machining and finishing. As a leading 17 4PH stainless steel supplier, we provide certified materials for projects across UAE, Oman, and Saudi Arabia.

17‑4PH H1150 stainless steel, also known as 17 4PH material, is a martensitic, precipitation hardening alloy. It combines high strength with corrosion resistance and excellent mechanical stability.

Technical Specifications

Chemical Composition
  • Carbon (C): ≤ 0.07% – Limits carbide formation and retains toughness.
  • Silicon (Si): ≤ 1.00% – Adds strength and supports alloy stability.
  • Manganese (Mn): ≤ 1.00% – Enhances toughness.
  • Phosphorus (P): ≤ 0.04% – Improves cleanliness and reduces brittleness.
  • Sulfur (S): ≤ 0.03% – Maintains weldability.
  • Chromium (Cr): 15.0‑17.5% – Provides corrosion resistance and strength.
  • Nickel (Ni): 3.0‑5.0% – Enhances toughness and stabilizes microstructure.
  • Copper (Cu): 3.0‑5.0% – Key element in precipitation hardening response.
  • Niobium + Tantalum (Nb+Ta): 0.15‑0.45% – Strengthens matrix and improves aging response.
  • Iron (Fe): Balance – Main matrix element.
Treatment
  • Solution Annealed (Condition A): Heated to ~1038°C (1900°F) for ~½ hour, then air or oil cooled to refine structure.
  • Precipitation Hardening (H1150): Aged at ~621°C (1150°F) for ~4 hours then air cooled to achieve high strength (~135‑170 ksi UTS).
  • Post‐Machining Stress Relief: After aging, the component may be stress relieved or cold worked to minimize residual stresses and ensure dimensional stability.
  • Fabrication Advice: Material can be welded in Condition A; the welds should then be aged. For best corrosion resistance in marine environments, use H1150 or above.
