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.
17-4 PH® Powder Applications
17-4 PH® is ideal for manufacturing chemical processing components, coupling, fasteners, gas turbines, gears, hydraulic actuators, pump shafts, rocket and missile components, and valve stems and wear rings.
17-4 PH® Powder Advantages
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. Other benefits include:
-
High Strength and Hardness: Achieves excellent mechanical properties after heat treatment.
- Corrosion Resistance: Resists corrosion in both mild and moderate environments.
- Heat Treatable: Properties can be tailored via age hardening.
