Adinox Overseas is a leading supplier and exporter of 17-4 PH Stainless Steel Sheets, offering unmatched quality and performance for critical industrial applications. Also known by its UNS S17400 designation, 17-4 PH is a precipitation-hardened martensitic stainless steel that delivers an exceptional combination of high strength, excellent corrosion resistance, and superior mechanical properties. These sheets are widely used in aerospace, nuclear, marine, and chemical processing industries due to their outstanding performance under both corrosive and high-stress conditions.
Manufactured in accordance with ASTM A693 Type 630, our 17-4 PH Sheets are heat treated to achieve high tensile strength while retaining good toughness. The addition of copper, nickel, and chromium in the composition allows the alloy to be precipitation hardened through heat treatment, giving it mechanical strength that surpasses many other stainless steel grades. These sheets also exhibit low distortion during heat treatment, making them ideal for applications requiring dimensional stability.
At Adinox Overseas, our stainless steel sheets are processed with utmost precision to meet national and international quality standards. The 17-4 PH stainless steel sheets we provide are available in a variety of thicknesses, widths, and lengths to suit specific project needs. They offer excellent machinability in the annealed condition and can be welded using standard techniques, although post-weld heat treatment is recommended to restore mechanical properties.
17-4 PH Sheets supplied by Adinox Overseas are especially valued in environments where strength and moderate corrosion resistance are required. From aircraft structural components to nuclear reactor parts and offshore platforms, these sheets provide the durability and reliability necessary for demanding applications. We ensure all our sheets are thoroughly tested and certified with proper traceability, meeting the expectations of clients around the globe.
