15-5PH Stainless Steel (UNS S15500 / WNR 1.4545) is a precipitation hardening martensitic stainless steel offering high strength, excellent toughness, and superior corrosion resistance. It is widely used in aerospace, oil & gas, marine, petrochemical, and defense industries, where materials must withstand harsh environments and high mechanical loads.

At Nifty Alloys, based in Dubai, UAE, we are a leading supplier, stockist, and exporter of 15-5PH Stainless Steel round bars, plates, sheets, and forgings. Our products are sourced from reputed mills and delivered with mill test certificates (MTCs), ensuring full compliance with global standards.  

What is 15-5PH Stainless Steel?

15-5PH (short for 15% Chromium – 5% Nickel Precipitation Hardening) is a martensitic stainless steel developed as an improved version of 17-4PH. It provides:

• Higher toughness across larger sections
• Better corrosion resistance in many environments
• Improved mechanical properties due to refined microstructure

This makes 15-5PH an ideal material for critical engineering applications in Dubai and GCC industries.
