The S17700 alloy has been available for many years and has found application in aerospace and
many spring type applications requiring high strength.
17-7PH precipitation hardening alloy may be formed in a soft austenitic condition and hardened to
a high strength level by low temperature heat treatments.
The low temperature allows minimum distortion compared to conventional quench and temper
hardening processes. In addition to material produced by the standard refining procedures,
material which has been vacuum arc or electroslag remelted is available for further increase
in resistance to fatigue,for those applications subject to cyclic stresses.
PRODUCT FORMS
17-7PH precipitation hardening alloy is furnished as plate, sheet and strip .
In all forms, the material is furnished in the annealed condition.
In strip form, the material may be provided in a cold rolled condition suitable for
direct precipitation hardening heat treatment at 900°F (482°C).
