PH15-7Mo Cold Rolled Stainless Steel Strip In Coil UNS S15700 Sheet

PH15-7Mo Cold Rolled Stainless Steel Strip In Coil UNS S15700 Sheet

PH15-7Mo Precipitation Hardening Alloy (S15700, AISI Type 632, EN 1.4574, DIN X) 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 S15700 alloy is similar to 17-7PH Precipitation Hardening Alloy (S17700).
The S15700 alloy is designed with substitution of approximately 2.0 percent molybdenum for 2.0 percent
chromium in the S17700 alloy.

This results in somewhat higher room and elevated temperature strength for the S15700 alloy.
The S15700 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.
In addition to material produced by the standard refining procedures, material which has been

vacuum arc or electroslag re-melted is available for further increase in resistance to fatigue,

for those applications subject to cyclic stresses.

Specifications
