17-4PH Round Bars Introduction 17-4PH (also known as UNS S17400 or 1.4542) is a precipitation hardening martensitic stainless steel widely used for its high strength, good corrosion resistance, and excellent mechanical properties at temperatures up to 600°F (316°C). The 'PH' in 17-4PH stands for precipitation hardening, and the alloy contains approximately 17% chromium and 4% nickel, along with copper and niobium, which contribute to its hardening properties. Round bars made from 17-4PH are extensively used in critical applications where strength and corrosion resistance are essential. Size and Length 17-4PH round bars are available in a variety of sizes and lengths to suit different industrial needs. Common specifications include: Diameters: Typically range from 3mm to 300mm (1/8” to 12”) Lengths: Standard lengths are 3 meters (10 feet) or 6 meters (20 feet), but custom lengths can be supplied on request Finish: Cold-drawn, peeled and turned, or centerless ground, depending on the application requirements Tolerance: Based on ASTM A564 / A693 standards or specific client requirements Uses 17-4PH round bars are valued across industries for their combination of high strength and corrosion resistance, particularly in environments requiring minimal distortion after heat treatment. Key applications include: Aerospace components: Turbine blades, engine parts, and structural components Nuclear and power generation: Reactor parts, steam turbines Oil & gas: Valve parts, pump shafts, downhole tools Medical instruments: Surgical tools, orthopedic implants Automotive and marine: Shafts, gears, propeller shafts General engineering: Fasteners, couplings, machine parts 17-4PH round bar supplier 17-4PH stainless steel rod manufacturer 17-4PH round bar stockist 17-4PH steel bar distributor UNS S17400 round bar supplier 17-4PH stainless bar wholesale Buy 17-4PH round bars online 17-4PH round bar ASTM A564 supplier 17-4PH stainless steel rod exporter Precipitation hardened steel 17-4PH manufacturer 17-4PH round bar supplier 17-4PH round bar manufacturer 17-4PH round bar exporter 17-4PH round bar distributor Buy 17-4PH round online 17-4PH round bar sizes and grades ASTM A564 17-4PH round bar UNS S17400 round bar specification 17-4PH round mechanical properties 17-4PH round bar heat treatment 17-4PH round for aerospace 17-4PH round for oil and gas 17-4PH shaft material 17-4PH stainless for machining 17-4PH corrosion resistant bar Conclusion 17-4PH round bars offer an excellent balance of mechanical strength, hardness, and corrosion resistance, making them suitable for high-performance and demanding applications.
