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.
