17-4 PH®, a wrought compressed stainless steel powder, combines high strength and high hardness with excellent corrosion resistance, fracture toughness and heat treatment properties. When machined, 17-4 PH® produces long, gummy chips. While soft and ductile in an annealed condition, it is capable of high hardness properties with a single precipitation or aging treatment. Applications 17-4 PH® is ideal for manufacturing aircraft fittings, braces, chemical processing components, coupling, fasteners, gas turbines, gears, hydraulic actuators, jet engines, nuclear reactor parts, pump shafts, rocket and missile components, valve stems and wear rings. The physical properties of 17-4 PH® stainless steel make it weldable by common fusion and resistance techniques. Among members of the precipitation hardening class of stainless steels, 17-4 PH® has the best weldability.

SS 17/7 PH® is a precipitation hardenable stainless steel that is formable and also capable of meeting high strength requirements. It is utilized in applications that require both high strength and good corrosion resistance. The alloy is classified as semi-austenitic to distinguish the soft phase (austenite) available for ease of forming from the high strength phase (martensite) usually achieved by heat treatment. The alloy can be formed from the annealed temper but due to a rapid work hardening rate may not be deep drawn without intermediate annealing. It is joined by most arc and resistance methods used for stainless steel. It should not be fusion welded unless shielded by inert gas to prevent oxidation of aluminum.

SS 17/4 PH® is a precipitation hardenable Martensitic stainless steel with high strength, and good corrosion resistance. This makes it perfect for use in metal diaphragms, for both aerospace sensors and burst discs. It is easily heat treated from the annealed temper. The corrosion resistance of the alloy is comparable to SS 302. It is heat treated at 900° F/1 Hour for highest strength. Other thermal treatments can be utilized to provide greater toughness and improved formability. Joining of the alloy is accomplished by the usual methods that are effective for stainless steel. Available Sizes: SS 17/4 PH® is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.050” (0.0254 mm to 1.27 mm) and widths up to 12.0” (304.8 mm). The material conforms to AMS 5604, ASTM A693 and UNS S17400.
