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.

L-605™ is a nonmagnetic cobalt-based chromium-tungstennickel alloy that has excellent corrosion and oxidation resistance, and high strength at both room and elevated temperatures. Through work hardening, high strength levels can be obtained. L-605™ has a minimal heat treatment response, but can be used in the cold worked and aged condition. Applications include medical implant devices, springs, valves, and engine components for the aerospace industry. As a result of its high tungsten content, L-605TM is radiopaque, which is beneficial for implant medical devices, such as stents. Because of the alloy’s high work hardening rate, only minimal reductions can be taken before solution annealing will be required. L-605TM is very resistant to oxidation and scaling at elevated temperatures, and is nonmagnetic in all conditions. L-605™ is produced by vacuum induction melting followed by electroslag remelting (VIM-ESR), and as such, has a low nonmetallic inclusion level.
