17-7PH 1.4568 X7CrNiAl17-7 631 Cold Rolled Stainless Steel Sheet Slit Strip In Coil
17-7PH / 1.4568 is an austensitic chromium nickel stainless steel with aluminum addition.
Precipitation hardening grade with high strength and hardness, good corrosion resistance and
satisfactory formability (depending on heat treatment/”Condition”).
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.
For e.g. retaining rings, springs, valves and gears, aircraft parts.

This stainless 17-7PH 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.
