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.
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.
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.
