17-4PH Stainless Steel | Supplier & Stockist in UAE – Nifty Alloys LLC

 

17-4PH stainless steel, also known as UNS S17400 or Type 630, is a premier precipitation-hardening martensitic stainless steel. Renowned for its exceptional combination of high strength, hardness, and corrosion resistance, this alloy is a cornerstone material for demanding industrial applications. It provides the mechanical strength of a heat-treated alloy steel while retaining the corrosion resistance of a stainless grade.

Nifty Alloys LLC is a trusted 17-4PH stainless steel supplier in the UAE, providing certified materials that meet rigorous international standards. We stock and supply 17-4PH in various forms, including round bars, plates, and custom-machined components, to serve the aerospace, marine, chemical processing, and energy sectors. Our commitment is to deliver materials that meet your exact specifications with full traceability and technical support.

What is 17-4PH Stainless Steel?

17-4PH is a chromium-nickel-copper precipitation-hardening stainless steel. Its designation comes from its chemical composition, which includes approximately 17% chromium and 4% nickel. The "PH" signifies that its superior mechanical properties are achieved through a precipitation hardening, or aging, heat treatment process.

This treatment allows the alloy to develop very high tensile strength and hardness. The process begins with a solution annealing treatment, followed by a single, low-temperature aging cycle. This cycle precipitates fine, copper-rich particles within the steel's martensitic matrix, which significantly strengthens the material. The result is an alloy that offers an outstanding balance of strength, toughness, and corrosion resistance, making it suitable for complex and high-stress components.

 

Key Features of 17-4PH Stainless Steel

 

The widespread adoption of 17-4PH stems from its unique combination of beneficial characteristics. These features make it a reliable and cost-effective solution for many critical components.

  • High Strength and Hardness: Achieves tensile strengths exceeding 1310 MPa and hardness levels up to 40 HRC, ideal for high-stress applications.
  • Excellent Corrosion Resistance: Offers corrosion resistance comparable to Grade 304 stainless steel in many environments, including marine and mild chemical settings.
  • Good Mechanical Properties at Elevated Temperatures: Maintains useful strength and stability at temperatures up to 315°C (600°F).
  • Excellent Toughness: Can be aged to achieve high levels of toughness and impact resistance, particularly in conditions like H1150.
  • Simple Heat Treatment: The single-step, low-temperature aging process is straightforward and results in minimal distortion.
  • Good Weldability and Machinability: Can be readily welded and machined in the solution-annealed (Condition A) state.
