1.4564 / 17-7PH® is an austenitic chromium-nickel stainless steel with aluminum addition.
Excellent fatigue properties, good corrosion resistance, good formability and minimum distortion upon heat treatment. It is easily formed in the annealed condition, hardened to high strength levels by heat treatments to condition CH900, RH950 or TH1050. The exceptional high strength of condition CH900 offers many new advantages where limited ductility and workability are permissible. In its heat treated condition, this alloy provides exceptional mechanical properties at temperatures up to 480 °C.
