SUS632 Cold Rolled Stainless Steel Strip PH15-7Mo Stainless Steel Coil
SUS632 Cold Rolled Stainless Steel Strip PH15-7Mo Stainless Steel Coil
Precipitation hardening stainless steel SUS632, PH15-7Mo
with high strength and hardness, good corrosion resistance, and satisfactory formability.
PH15-7Mo stainless alloy is particularly beneficial for a wide range of applications that
include retaining rings, springs, diaphragms, aircraft bulkheads, welded and brazed honeycomb
paneling and other aircraft components requiring high strength at elevated temperatures.

Heat treatment
PH 15-7Mo Stainless Steel requires three essential steps in heat treating:
- 1) austenite conditioning,
- 2) cooling to transform the austenite to martensite
- and 3) precipitation hardening.
The material normally is supplied from the mill in Condition A.
After fabrication, an austenite conditioning treatment is followed by a transformation treatment to
either Condition T or Condition R 100. Then the material is precipitation
hardened to either Condition TH 1050 or Condition RH 950 to develop fully useable properties.
To obtain the highest mechanical properties in this alloy, Condition A material is transformed to
martensite at the mill by cold reduction to Condition C.
After fabrication by the user, hardening to Condition CH 900 is accomplished with a single low-temperature heat treatment.
