17-4PH Stainless Steel: A Comprehensive Guide for Industrial Buyers
17-4PH stainless steel, also known as 17/4PH, is a premier precipitation hardening martensitic stainless steel renowned for its exceptional combination of high strength, excellent corrosion resistance, and good toughness. This versatile alloy can be heat-treated to various strength and hardness levels, making it suitable for some of the most demanding industrial applications. The different heat treatment conditions, such as H900, H1025, H1075, and H1150, allow engineers to tailor its properties to specific operational requirements.
As a leading 17-4PH stainless steel supplier in UAE, Nifty Alloys LLC provides a comprehensive inventory of this high-performance material to clients across the United Arab Emirates and worldwide. We deliver certified, traceable products that meet rigorous international standards, ensuring reliability for your critical projects.
What is 17-4PH / 17/4PH Stainless Steel?
17-4PH stainless steel is a chromium-nickel-copper precipitation hardening stainless steel (PH stainless steel). Its name is derived from its chemical composition, which nominally includes 17% chromium and 4% nickel. The inclusion of copper allows the material to be hardened through a precipitation or age-hardening heat treatment process.
During this process, microscopic copper-rich precipitates form within the steel's martensitic matrix. This phenomenon obstructs dislocation movement, significantly increasing the material's strength and hardness. As a result, AISI 630 stainless steel (another designation for 17-4PH) is specified for components where both high strength and superior corrosion resistance are non-negotiable. Its performance profile makes it a superior choice over standard martensitic grades like 410 and 420.
