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, based in Dubai, UAE, we are a trusted supplier, stockist, and exporter of 17-4PH Stainless Steel round bars, plates, sheets, and forgings. With ready stock and global sourcing, we provide top-quality 17-4PH Stainless Steel that meets international standards, delivered with mill test certificates (MTCs).
17-4PH (short for 17% Chromium – 4% Nickel Precipitation Hardening) is a martensitic stainless steel that can be hardened by heat treatment. It combines corrosion resistance similar to 304 and 316 stainless steels with the high strength of alloy steels, making it one of the most versatile stainless steels available.
Engineers in Dubai and across the GCC rely on 17-4PH for components that require high fatigue strength, resistance to stress corrosion cracking, and good toughness.
