Material 17-7PH Cold Rolled Stainless Steel Sheet SUS631 Strip In Coil
Precipitation Hardening (PH) stainless steels are classified as martensitic or semi-austenitic.
They develop their high strength and hardness through a variety of heat treatments resulting in a
very high strength-to-weight ratio.
Semi-austenitic grades are 17-7PH and PH 15-7 Mo.
They are austenitic in the annealed state, and martensitic in the hardened condition.
Martensitic grades include 17-4PH and 15-5PH. The PH grades achieve high tensile properties in heat treated conditions.
Applications for PH steels include aerospace components, flat springs, and retaining rings.
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.

17-7PH stainless grade combines the following characteristics:
17-7 PH 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.
