17-7 PH

MEDICAL

Materials

17-7 stainless steel is a precipitation-hardening stainless steel alloy that offers a combination of high strength, corrosion resistance, and formability. It contains significant amounts of chromium, nickel, aluminum, and manganese. While not as widely used in the medical industry as some other stainless steel grades, 17-7 can find applications in specific medical devices and components.

Typical Chemistry

​​​

  • Chromium (Cr): 16.0-18.0%

  • Nickel (Ni): 6.75-7.75%

  • Aluminum (Al): 0.75-1.50%

  • Manganese (Mn): 1.00% max

  • Silicon (Si): 1.00% max

  • Phosphorus (P): 0.040% max

  • Sulfur (S): 0.030% max

​

While 17-7 is not as commonly utilized in the medical industry as other stainless steel grades like 316L or 17-4, it can still find applications in specific medical devices and components. Some potential uses include:

​​

Use in the Medical Industry:

​

Medical Springs and Fasteners: The high strength and corrosion resistance of 17-7 make it suitable for manufacturing springs, fasteners, and other small components in medical devices.

​

Orthopedic Devices: In certain orthopedic applications, where a combination of strength and corrosion resistance is required, 17-7 stainless steel may be used for components like bone screws and small implantable devices.

​

Instrumentation: The alloy can be employed in the fabrication of certain medical instruments and tools that require a balance of strength and formability.

​

Diagnostic Equipment: Components for diagnostic equipment, such as sensors and small structural elements, may be made from 17-7 stainless steel.
