17-4PH Stainless Steel (UNS S17400 / 1.4542) is a precipitation hardening martensitic stainless steel known for its excellent combination of high strength, corrosion resistance, and toughness. It is widely used in aerospace, oil & gas, petrochemical, marine, defense, and engineering industries, where reliability under extreme conditions is essential.
At Nifty Alloys LLC, we are a leading supplier, stockist, and exporter of 17-4PH Stainless Steel in Dubai, UAE. We supply this premium grade in multiple forms such as round bars, plates, sheets, pipes, and forgings, sourced from reputed mills and delivered with Mill Test Certificates (MTCs).
17-4PH Stainless Steel is a chromium-nickel-copper martensitic stainless steel that achieves strength through a precipitation-hardening (aging) process. It delivers a perfect balance of strength, ductility, corrosion resistance, and ease of fabrication.
This grade is often chosen over standard 304 Stainless Steel or 316 Stainless Steel when high mechanical strength and wear resistance are required, making it an excellent alternative to traditional martensitic grades.
