AMS 5604K specification covers a corrosion-resistant steel in the form of sheet, strip, and plate 4.0 inches (102 mm) and under in nominal thickness. 17-4PH Stainless Steel Sheet (UNS S17400) is known for its good corrosion resistance, excellent strength, and high hardness. The wear-resistant characteristics of the alloy are outstanding. In sheet form, uses include aircraft skins and various aircraft parts. ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5604 17-4PH stainless steel sheet at factory-direct prices with full material traceability and fast global delivery.
Operating Conditions & Selection Criteria17-4PH stainless steel sheet is specified when designers require a versatile precipitation-hardening alloy with good corrosion resistance, excellent strength, high hardness, and outstanding wear resistance for aerospace and industrial sheet metal applications. Service Temperature Range: Excellent properties from cryogenic temperatures up to 315°C (600°F); good oxidation resistance to 650°C (1200°F) Strengthening Mechanism: Age-hardened through precipitation of copper-rich phases during simple single-step, low-temperature treatment Wear Resistance: Outstanding wear-resistant characteristics for demanding applications Corrosion Resistance: Good corrosion resistance comparable to 304 stainless steel Versatility: Highly versatile due to variety of heat treatments available (H900-H1150) Fabricability: Good machinability and fabricability, particularly in lower tempers Formability: Improved formability when heat-treated before cold working Weldability: Good welding capabilities using standard fusion and resistance methods Thickness Range: Available in sheet, strip, and plate up to 4.0 inches (102 mm)
ApplicationsAircraft Skins & Parts: Aerospace sheet metal components, aircraft skins, structural parts Aerospace Components: Engine parts, airframe hardware, fasteners, fittings Chemical Processing: Pump and valve components, process equipment Oil & Gas: Downhole tools, wellhead equipment (H1150 for sour service) General Industrial: Gears, shafts, bushings, molds, dies, wear-resistant components Nuclear: Reactor components, structural hardware
