AMS 5520, ASTM A693 Stainless Steel Strip Band SAE 632 S15700 PH15-7Mo
PH 15-7Mo Precipitation Hardening Alloy (S15700, AISI Type
632) is a chromium-nickel-molybdenum-aluminum
semi-austenitic precipitation hardening stainless steel used for
applications requiring high strength and a moderate
level of corrosion resistance.
The PH15-7Mo alloy is similar to 17-7PH Precipitation Hardening
Alloy (S17700).
The PH15-7Mo alloy is designed with substitution of approximately 2.0 percent molybdenum for 2.0 percent
chromium in the 17-7PH alloy.
This results in somewhat higher room and elevated temperature strength for the S15700 alloy.
The PH15-7Mo alloy has been available for a number of years and has found application in aerospace and
many spring type applications requiring high strength.
The PH15-7Mo 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 heat treatment required for developing high
strength allows minimum distortion compared to conventional quench
and temper hardening processes.
