17-4PH is a chromium-nickel alloy that has a 4% copper additive, which enables it to be hardened
by very low-temperature heat treatments known as precipitation hardening.
The high percentages of chromium and nickel give this alloy excellent corrosion resistance,
physical properties, and a high level of strength at temperatures up to 800° F.
The major advantage of low temperature heat treatments is the elimination of distortion and scaling.
17-4PH has excellent mechanical properties and may easily be welded, deep drawn, forged,
and severely formed.
Chemical composition of grade 17-4PH stainless
This alloy is excellently suited for applications requiring high strength, good corrosion resist-ance
and good resistance to seizing and galling. 17-4PH finds extensive use in the aircraft and missile fields,
for motor shafts, instrument parts, gears, and etc.
The corrosion resistance of 17-4PH is slightly less-than-the superior resistance of the chro-mium-
nickel grades, but is somewhat higher than the straight chromium grades.
It possesses very good corrosion resistance against all atmospheric conditions.
Finish and heat treatment affect the level of corrosion resistance beneficially.
