PH 15-7Mo Stainless Steel is a semi-austenitic, precipitation-hardening stainless steel that
provides high strength and hardness, good corrosion resistance and minimum distortion on heat treatment.
It is easily formed in the annealed condition and develops an effective balance of properties by simple heat treatments.
For applications requiring exceptionally high strength, PH 15-7Mo Stainless Steel in Condition CH 900 is
particularly useful for applications with limited ductility and workability.
In its heat-treated condition, this alloy provides excellent mechanical properties at temperatures up to 900 °F (482 °C).
Its corrosion resistance is superior to that of the hardenable chromium types.
In some environments, corrosion resistance approximates that of the austenitic chromium-nickel stainless steels.
Fabricating practices recommended for other chromium-nickel stainless steels can be used for PH 15-7Mo Stainless Steel.
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.
