What are 17-4 PH Forgings?

17-4 PH stainless steel is a martensitic precipitation-hardening alloy widely used in aerospace, biomedical, and nuclear industries thanks to its high strength and excellent corrosion resistance. Forgings with this alloy are known for their exceptional fatigue resistance, flexibility, and stress corrosion cracking resistance. 17-4 PH can be easily machined and welded and is often chosen for its wide range of heat treatment options.

Forgings made with 17-4 PH stainless steel offer several advantages over other forgings. The forging process can create shapes for applications ranging from oil drilling equipment, pump components, surgical instruments, and even mobile phone cases. They are extremely versatile, providing enhanced mechanical properties through a range of heat treatment options by enriching a larger amount of their material, making them very strong and able to withstand various types of stress, including tension, compression, torsion, and bending stress. 

Applications of 17-4 PH Forgings

17-4 PH Forgings are used in various applications, such as:

Aerospace and Defense: forgings of turbine blade discs, spinners, compressor discs and other structural parts.

Energy and Oil & Gas: forgings for valve stems, pump shafts, and flanges.

Marine: forgings for propeller shafts, offshore platforms, and underwater robotics.

Medical: forgings used for surgical instruments, implantable devices that include screws, pins and other structural pieces.

Automotive: forgings for connecting rods, shock absorbers, and suspension components.

These are just a few examples of the versatile applications of 17-4 PH forgings.

Benefits of 17-4 PH Forgings

Forgings made from 17-4 PH stainless steel provide several advantages, including:

High-strength: Forgings with 17-4 PH SS exhibit exceptional strength and hardness, making them ideal for applications that require high-stress loads or fatigue resistance.

Corrosion resistance: 17-4 PH SSforgings are highly corrosion-resistant, which means they can withstand exposure to moisture, chemicals and other hazardous elements.

Ductility: These forgings exhibit good ductility even when subjected to high-stress loads, providing flexibility and protection against cracking.

Low maintenance: With their excellent corrosion resistance and strength properties, 17-4 PH SS forgings require low maintenance and can have a long-lasting lifespan.
