17-7 PH is a precipitation hardening semi-austenitic stainless steel.
It is able to develop a very high strength due to the strengthening of aluminium particles.
It is usually found in strip or wire form for spring applications.

(Listed as Grade 631-UNS S17700)
This grade combines the following characteristics:
17-7PH provides a combination of very high strength and moderate corrosion resistance.
Its metallurgy is complex involving several stages of processing to develop the necessary microstructure.
The highest level of strength is achieved by cold working to produce martensite followed by an ageing treatment at about 480°C.
This restricts the use of the grade to thin sheet and wire products.
Other heat treatment conditions are also available to produce softer and more ductile material.
Applications which illustrate these features include:
Springs, Belleville washers, aerospace, orthodontic wire, strain gauge, load cell, pressure transducer.
